During what type of phase change does a substance release energy to its surroundings?
Answers
solid The state of matter in which materials have a
definite shape and a definite volume.
liquid The state of matter in which a material has a
definite volume but not a definite shape.
gas The state of matter in which a material has
neither a definite shape nor a definite volume.
kinetic energy The energy that an object has due to its motion.
pressure The result of force distributed over an area.
absolute zero This temperature is equal to 0K on the Kelvin
terperature scale.
Charles's law States that the volume of a gas is directly
proportional to its temperature in kelvins if the
pressure and the number of particle of the gas
are constant.
Boyle's law States that the volume of a gas is inversely
proportional to its pressure if the temperature
and the number of particles are constant.
phase change The reversible physical change that occurs when
a substance changes from one state of matter to
another.
endothermic A type of change where the system absorbs
energy from its surroundings.
heat of fusion The amount of energy a substance must absorb
in order to change from a solid to a liquid
exothermic A description of a change in which a system
releases energy to its surroundings.
vaporization The phase change in which a substance changes
from a liquid to a gas.
heat of vaporization The energy a substance must absorb in order to
change from a liquid to a gas.
evaporation The process that changes a substance from a
liquid to a gas at temperatures below the
substance's boiling point.
vapor pressure The pressure caused by collisions of particles in
a vapor with the walls of a container.
condensation The phase change in which a substance changes
from a gas or vapor to a liquid.
sublimation The phase change in which a substance changes
from a solid to a gas or vapor without changing
to a liquid first.
deposition The phase change in which a gas or vapor
changes directly into a solid without first
changing into a liquid.
