Re: Endothermic or Exothermic
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

Re: Endothermic or Exothermic
Condensation is exothermic. This is because heat is released when a substance changes from gas to a liquid and it is condensing.

Re: Endothermic or Exothermic
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.

Re: Endothermic or Exothermic
Condensation is an exothermic reaction because heat is being released during the phase change from a gas to liquid.

Re: Endothermic or Exothermic
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).

Re: Endothermic or Exothermic
condensation is an exothermic process because the water vapor molecules lose energy as heat

Re: Endothermic or Exothermic
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.

Re: Endothermic or Exothermic
Condensation is an exothermic reaction. As the water molecules change phase from gas to liquid, energy is released.

Re: Endothermic or Exothermic
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.
Re: Endothermic or Exothermic
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.

Re: Endothermic or Exothermic
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.

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

Re: Endothermic or Exothermic
Its exothermic, because it releases heat and is the opposite of the process that requires heat to change phase.

Re: Endothermic or Exothermic
Solid --> Liquid --> Gas is endothermic (surroundings get warmer)
Gas --> Liquid --> Solid is exothermic (surroundings get cooler)
Gas --> Liquid --> Solid is exothermic (surroundings get cooler)

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