What best explains what happens when liquid water evaporates to form water vapor?
When water molecules at the surface gain sufficient energy they can escape in the atmosphere.The energy of water molecules increase by a temperature increase and some molecules at the surface can escape in the atmosphere.
What happens when heat is add to steam?
Adding heat to water vapor will just cause the molecules to gain energy and move faster. As long as the amount of energy added is not extraordinary, this is all that will happen. At extremely high temperatures, the water vapor may convert to hydrogen and oxygen gas.
Molecules at the surface of a liquid can enter the vapor phase only if?
C, the energy level...
What Water molecules in ice have more kinetic energy that water molecule and vapor?
more
What happens when water changes from a solid to a liquid to a vapor?
loses energy
What is evaporation do when its outside?
Evaporation- The process which molecules at the surface of a liquid, such as water, absorb enough energy to change to a gaseous state, such as water vapor.
What causes particals to evaporate and leave the surface of a liquid?
Molecules at the surface of a liquid absorb kinetic energy (kinetic energy used to disrupt intermolecular forces) and evaporate. (vapor pressure is exerted)

What happens to the molecules of water vapor when the temperature of the gas cools?
the water vapor turns to liquid
What happens to the speed of molecules in water vapor when it condenses to form a liquid?
The molecules slow down.
What happens to the speed of molecules in water vapor when it condenses to form of a liquid?
The molecules slow down.
Describe the role of energy when ice melts and when vapor condences to form liquid water?
When water molecules melt, energy is absorbed. When water molecules evaporate, energy is also absorbed. When water molecules condense energy is released. When water molecules freeze energy is also released.
Are water molecules the same as water vapor?
Water vapor is composed of water molecules with enough energy (temperature) to support that phase, as opposed to liquid or solid phases.
What does water need energy for to become water vapor?
Intermolecular forces, i.e. hydrogen-bonds, have to be broken down in order for water molecules to escape to the vapor phase. Energy is needed in the process to set water molecules free.
What happens when heat is add to steam?
Adding heat to water vapor will just cause the molecules to gain energy and move faster. As long as the amount of energy added is not extraordinary, this is all that will happen. At extremely high temperatures, the water vapor may convert to hydrogen and oxygen gas.
When water goes through condensation do the molecules gain or lose energy?
When water gains energy the water molecules turn into vapor also known as Evaporation.
