What is the heat of vaporization?
The amount of heat required to convert a liquid into a gas at a constant temp and pressure.
What is the heat of fusion?
The amount of heat required to convert a solid at its melting point into a liquid without an increase in temp.
What is the sublimation?
The process by which a solid changes directly to a gas
What is condensation?
The process by which gas changes to a liquid
What is evaporation?
The temp at which a substance changes from a liquid to a gas below the boiling point.
What is the boiling point?
The temp at which a substance changes from a liquid to a gas.
What is the melting point?
The temp at which a substance changes from a solid to a liquid.
What are intermolecular forces?
The electromagnetic forces that act between molecules determine the phases of the molecules at a given temp.
What is heat?
The energy transferred between objects that are at different temps; specifically, measure of total kinetic energy of the particles in an object
What is temperature?
a measure of how hot or cold something is; specifically, a measure of the average kinetic energy of the particles in an object.
