Across
when a gas or vapor changes directly into a solid without first changing to a liquid, the phase change is called
heat absorbed by a unit mass of a given solid at its melting point that completely converts a solid to a liquid
states that the volume of a gas is directly proportional to its temperature in kelvins if the pressure and the number of particles of gas are constant
is the phase change in which a substance changes from a solid to a gas or vapor without changing to a liquid first
the heat absorbed per unit mass of a given material at its boiling point that completely converts the material to a gas
state of matter in which a material has neither a definite shape nor a definite volume
reversible physical change that occurs when a substance changers from one state of matter to another
state of matter in which materials have a definite shape and a definite volume
energy an object has due to its motion
change, they system absorbs energy from its surroundings
Down
the phase change in which a substance changes from a gas or vapor to a liquid
change, system releases energy to its surroundings
the pressure caused by the collision of this vapor and the walls of the container
a temperature of 0 on kelvin scale is called
phase change in which a substance changes from a liquid into a gas
the state of matter in which a material has a definite volume but not a definite shape
process that changes a substance from a liquid to a gas at temperatures below the substance boiling point
result of a force distributed over an area
states that the volume of a gas is inversely proportional to its pressure if the temperature and the number of particles are constant
