Change of State

Over the last month, we examined water in its different states. Specifically, we looked at liquid dew and gaseous water vapor. We also explored the process where water changes state. This question has 2 parts:

1) What is the difference between evaporation and condensation?

2) What is the role of heat transfer in these processes?

Explain your thinking!

  1. The difference between evaporation and condensation is that condensation is when heat energy is released by water and the water vapor forms into liquid water. Evaporation is when heat energy is absored and liquid water forms into water vapor.

  2. the difference between evaporation and condensation is evaporation is were a liquid turns into a gaseous form of water and condensation is were gas or water vapor turns into a liqiud form of water.

  3. The difference between evaporation and condensation is that evaporation is when the liquid turns into a gas and condensation is when gas or water vapor transforms into a liquid or water.

  4. The difference between evaporation and condensation is that evaporation is when a liguid turns into a gas and then goes up to the sky cools and transforms from a gas to a liguid. they are both part of the water cycle but involve in two different states of matter and different properties.
