Endothermic or Exothermic

[torialmquist1F]

Is condensation endothermic or exothermic and why?

[Kennedy Moore 1D]

Condensation is an exothermic process, as the water looses heat in order to turn from vapor to a liquid, which is released from the system into the surroundings

[Julianna Thrasher 1B]

Condensation is exothermic. This is because heat is released when a substance changes from gas to a liquid and it is condensing.

[lindsay lathrop 2C]

Condensation is exothermic. One reason we know this is because its counterpart phase change is vaporization and vaporization is endothermic. A more direct reason would be that in condensation the particles are beginning to move a lot slower, vibrate a lot less and more hydrogen bonds are forming. These all are releasing energy, as a lot less energy is needed to move at these slower speeds etc. And when energy is released it is exothermic.

[Phi Phi Do 2E]

Condensation is an exothermic reaction because heat is being released during the phase change from a gas to liquid.

Condensation is exothermic! It's easy to just think of where the heat is going (gas has more heat/energy than a liquid, so the heat must be leaving the gas).

[Emma Miltenberger 2I]

Condensation is exothermic because bonds are being formed.

[Arshpreet Sandhu 1B]

exothermic due to heat release

[Joyce Gu 1E]

condensation is an exothermic process because the water vapor molecules lose energy as heat

[IsabelLight2H]

How do I know if it's endothermic or exothermic?

[Arta Kasaeian 2C]

Condensation is the transformation of gas to liquid, for which energy is released, making it exothermic and within an equilibrium, an increase in temperature would favor the reactant side.

[Hilda Sauceda 3C]

Exothermic because heat is being released

[varunhariharan]

Condensation is an exothermic reaction. As the water molecules change phase from gas to liquid, energy is released.

[Hannah Pham 1D]

Condensation is exothermic because it releases heat. You see this in real life when you have a cold drink and condensation forms water droplets on the side of the cup.

[Anna O 2C]

As stated above, condensation is exothermic. When you look at it from a molecular standpoint, the molecules are transitioning from the gas phase to the liquid phase. Individual atoms are thus coming together and bonding with each other, a process that release excess heat as the bonded molecule is more stable and requires less energy. This energy is then given off as leftover heat.

[Sarah Fatkin 4I]

Condensation is exothermic. For example, like Dr. Lavelle said in lecture, when steam condenses from vapor to liquid, it releases heat. This is why steam burns are worse than burns from liquid water.

[Philipp_V_Dis1K]

Exothermic, one can look at the reverse, which is endothermic, when one sweats and the body heat is used up to vaporize the sweat.

[Samantha Chang 2K]

Condensations is an exothermic process!

[805087225]

Its exothermic, because it releases heat and is the opposite of the process that requires heat to change phase.

[Kirsty Star 2H]

Solid --> Liquid --> Gas is endothermic (surroundings get warmer)
Gas --> Liquid --> Solid is exothermic (surroundings get cooler)

[IsabelLight2H]

How do I know if it's endothermic or exothermic if there's no delta H given?
