Evaporation, Vaporization, and Condensation

What is heat
flow of energy due to differences in temperature
what does the liguid to gas transiltion phase (evaporation or vaporization) require
addition of heat
what does the gas to liguid transiltion phase (condensation) require
removal of heat
How does vaporization occur?
Through a phase transition.  The bonds between atoms in the water are broken
What is a phase transition
It is an alteration in physical state between solids, liquids, and gases
How does condensation occur.
It occurs through a phase transition.  Bonds between the atoms are remade.  This occurs when heat is removed
What is the equation in phase transitions

H=mL

H=-mL (condensation)
