What is a solid? The state of matter in which materials have a definite shape and a definite volume.
What is a liquid? The state of matter in which a material has a definite volume but not a definite shape.
What is a gas? The state of matter in which a material has neither a definite shape nor a definite volume.
What is the kinetic theory? The energy an object had due to its motion.
What is pressure? The result of a force distributed over an area.
What is absolute zero? It is when the temperature is 0 degrees Kelvin.
What is Charle's law? It states that the volume of a gas is directly proportional to its temperature in kelvins if the pressure and the number of particles of the gas are constant.
What is Boyle's law? Robert Boyle. It states that the volume of a gas is inversely proportional to its pressure if the temperature and the number of particles are constant.
Does the temperature of a substance change during a phase change? No. It is never in the middle, it is the stage that it is going towards. For example if water is beginning to boil it is no longer the regular liquid state temperature. It is 212 degrees or more Farenheight because it is in the boiling state.
What does the energy do if it is endothermic? The energy is absobed from its surroundings if it is endothermic.

What does the energy do if it is endothermic? The energy is absobed from its surroundings if it is endothermic.
What is heat of fusion? The amount of heat required to convert a solid at its melting point into a liquid without an increase in temperature. Liquids release the same amount of heat when they turn in to a solid.
What are the two types of vaporization? Evaporation and Boiling point.
What does the energy do if it is exothermic? The energy is released from its surroundings if it is exothermic.
what is heat of vaporization? The amount of heat required to convert a unit mass of a liquid at its boiling point into vapor without an increase in temperature.

What is vapor pressure? The presser exerted by vapor in a liquid or solid phase.
condensation Gas to liquid-exothermic.
sublimation
What phase does deposition go in? Gas to solid-exothermic.
