Re: freezing
Freezing is an exothermic process because as bonds form, molecules are at a lower potential energy state, so energy is released as heat. In an exothermic reaction, there is a net release of heat.

Re: freezing
Freezing is an exothermic process because bond formation releases energy. On the other hand, breaking bonds requires energy so a process like melting would be endothermic.

Re: freezing
Freezing is exothermic because heat is released in order to make bonds, while heat is required to break bonds. That is why melting, on the opposite side, would be endothermic.

Re: freezing
Freezing is exothermic as hydrogen bonds forming releases energy. liquid --> solid means hydrogen bonds formed
Re: freezing
Freezing is a phase change that is considered an exothermic process as liquid releases energy to form solid.

Re: freezing
Freezing is when a liquid turns into a solid, so it is releasing energy to form bonds which means it is an exothermic process which means it has a change in enthalpy that is negative!
Re: freezing
Freezing is an exothermic reaction, as it is releasing heat (heat is being removed from the system) when it creates bonds in order to become a solid. With that, we know that its change in enthalpy is negative as a result. Hope that helps!
Re: freezing
Hi!
Freezing in exothermic. It's from liquid phase to solid phase, which means bond are formed, and in order to form bonds, energy is released.

Re: freezing
Freezing is exothermic since if something is freezed (liquid to solid), the thermal energy must decrease (or must be released).

Re: freezing
Freezing is exothermic. This is due to the fact that when a substance goes from liquid to solid, the particles are getting closer to closer and the reason for this is a formation of stronger bonds between the particles. As we know, bond formation releases energy, making freezing exothermic.

Re: freezing
It is first important to know that chemical reactions which release energy are exothermic while endothermic reactions absorb energy. As a result, freezing is an exothermic process since energy is being released. On the other hand, processes such as photosynthesis would be considered as endothermic since they absorb energy in the form of heat. I hope this helps!

Re: freezing
Freezing is exothermic. Since it's kind of hard to imagine cooling something as that substance releasing heat, a good way to get to this conclusion is thinking about its reverse: melting. We know that you heat something to melt it, meaning that it is endothermic. This means that its reverse (freezing) is exothermic. Furthermore, when water freezes into an ice cube, the temperature of water decreases in this phase change, which means that heat is being lost and thus released.

Re: freezing
Freezing is an exothermic process. This is because the liquid water will release heat energy in order to form Hydrogen bonds. Once these bonds are formed, the liquid water will turn into a solid ice.

Re: freezing
Freezing is an exothermic process; heat is released in order to create bonds and to change the liquid into a solid. Thus, the change in enthalpy is negative.
Re: freezing
Hello,
Freezing would be considered to be an exothermic process since bonds are being formed. Energy is released in the form of heat since the molecules are at a lower [potential energy state. Melting is an example of an endothermic process since breaking bonds requires energy. I hope this helped!

Re: freezing
freezing is exothermic because for an object to go from a liquid state to a solid state, the average KE of the particles need to decrease such that the particles have a greater chance of forming bonds with one another. As such, freezing requires a loss of heat, meaning it is an exothermic process
Re: freezing
Freezing is an exothermic phase change as forming bonds requires them to lose energy while breaking bonds requires energy.
Re: freezing
Freezing is an exothermic process as forming bonds does not require an influx of energy while breaking bonds does.

Re: freezing
I think the process of Freezing is exothermic because during the process the heat is released in order to make bonds. Usually while heat is required to break bonds which is why the process of melting would be endothermic.

Re: freezing
Since freezing is when intermolecular bonds form, and bond formations release energy (because bonds are more stable so the species will be at a lower potential energy), freezing is exothermic.

Re: freezing
Freezing is exothermic because heat is released to form bonds where the system becomes more stable. On the other hand, melting would be endothermic because it requires heat to break the bonds and initiate a phase change.

Re: freezing
Hi! Freezing is an exothermic process. Freezing is the process of a substance turning from liquid to solid, and bonds in solid substances are lot stronger than in liquid substances. Forming stronger bonds gives off energy, which is partially why the substance gives off heat to the surroundings. Each atom in the substance also loses kinetic energy when the substances freezes. This takes heat away from the system, making it an exothermic process. Hope that helps!

Re: freezing
Freezing is an exothermic process, as the phase change from a liquid to a solid involves the formation of more bonds. The formation of bonds releases energy/heat, and as such is an exothermic process.

Freezing is an exothermic reaction because energy is released when water turns into ice and energy is absorbed when ice turns into water.

Re: freezing
freezing is an exothermic reaction. the way i remember it is that heat is required to break bonds, and heat is let off when bonds are made. when a liquid is turning into a solid (or freezing), bonds are being made, so heat is being released, which means it is an exothermic phase change.

Re: freezing
Freezing accompanies the transition of a species from a liquid to a solid. Given that there is a net loss in energy (we know that solids have fewer degrees of freedom and overall less KE) we can roughly say that the system loses heat and dH < 0.

Re: freezing
Freezing would be exothermic as energy would be released from the molecules as the phase change is happening. It seems counterintuitive since ice is could to the touch, but this is because the ice is absorbing energy from your hands to turn back into a liquid. Hope this helps :)

Re: freezing
An exothermic reaction gives off heat. When you touch an ice cube, it melts and your hand feels cold. The cold sensation is caused when heat flows from your hand to the cube (melting is endothermic). If we imagine the opposite, if your hand was the temperature of a freezer, heat would flow from the cube to your hand, and the cube would freeze. This is why freezing is exothermic.

Hello,
Just as my peers mentioned, freezing is an exothermic process: when water becomes solid, it releases heat.

Re: freezing
Hello. Freezing is an exothermic process because in order for a phase change to occur you need a release of energy. In order for a liquid to transition into a solid you need heat to be removed. Hope this helps!

Re: freezing
Freezing is an exothermic process because as bonds are being formed, energy/heat is being released. In addition, melting is an endothermic process and because of this, this means that freezing is an exothermic process.

Re: freezing
Freezing is an exothermic process because energy/heat is being released while new bonds are forming. The reverse process, melting, is endothermic so it makes sense that freezing would be exothermic. Hope this helps!

Re: freezing
Freezing is exothermic because heat is being released as the substance is cooled and becomes a solid.
Re: freezing
Freezing is an exothermic process because energy is released as more intermolecular bonds are formed, putting the molecules at a lower energy state.

Re: freezing
Freezing is an exothermic process because the solidification allows for more bonds to form, releasing heat. When that heat is released, the substance internally cools.

Re: freezing
Because when freezing a liquid, the temperature needs to be colder to change states of being, heat and pressure are released making it an exothermic reaction. Since the heat cannot just disappear, it warms up its surroundings instead. In other words, the heat is removed to make the liquid cold enough to change into freezing.

Re: freezing
The reason freezing is exothermic is because more hydrogen bonds involving the hydrogen and oxygen atoms are being formed when molecules slow down. When bonds form, energy is released.

Freezing would be considered exothermic because bonds are needed to form and the forming of bonds releases heat. Endothermic on the other hand would require heat.

Re: freezing
An endothermic reaction is one that requires energy to occur while an exothermic reaction releases energy. The process of freezing would be an exothermic reaction because it is building a molecule to make it solid and to build those bonds and bringing those together would have a net release of energy as heat.

Re: freezing
Freezing would most definitely be an exothermic reaction because there are bond formations that result in a net loss of energy/heat.
