Phases of Matter

QuestionAnswer
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 no 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 kinetic energy? The energy an object has due to its motion.
What is pressure? The result of a force distributed over an area.
What is absolute zero? A temperature of 0 Kelvin.
What is Charles's Law? Charles's Law states that the volume of a gas is directly proportional to its temperature in Kelvin if the pressure and number of particles are constant.
What is Boyle's Law? Boyle's Law states that the volume of a gas is inversely proportional to its pressure if the temperature and number of particles are constant.
What is a phase change? The reversible physical change that occurs when a substance changes from one state of matter to another.
What is an endothermic change? A change in which the system absorbs energy from its surroundings.
What is heat of fusion? The amount of energy absorbed in an endothermic change.
What is an exothermic change? A change in which the system releases energy to its surroundings.
What is vaporization? The phase change in which a liquid changes to a gas.
What is heat of vaporization? The amount of energy absorbed during vaporization.
What is evaporation? The process that changes a substance from a liquid to a gas at temperatures below the substance's boiling point.
What is vapor pressure? The pressure caused by the collisions of a vapor and the walls of a container.
What is condensation? The phase change in which a substance changes from a gas to a liquid.
What is sublimation? The phase change in whicha substance changes from a solid to a gas or vapor without changing to a liquid first.
What is deposition? The phase change in which a gas or vapor changes directly to a solid.
