a definite volume
Change from a liquid to a gas.
vaporization
The pressure of a gas ___________ if the volume decreases and temperature is kept constant. (Boyle's law)
increases
A solid has ___________________ and a definite volume. (three words)
a definite shape
The energy an object has due to its motion.
kinetic energy
Change from a gas to a liquid.
Condensation
The amount of force applied per unit of area is ___________.
pressure
What happens when the motion of particles slows?
The particles are close together.
Measure the average kinetic energy of all particles in an object.
temperature
Change directly from a solid to a gas.
Sublimation
As the temperature of a gas increases, its volume _________ if pressure is kept constant. (Charles's law)
increases
What causes surface tension?
Attractive forces between particles.
The total potential and kinetic energy of an object.
thermal energy
Vaporization that occurs within a liquid is __________.
boiling
The ______ _______ _________ explains how particles in matter behave.
Kinetic Molecular Theory
List the states of matter in order of increasing distance between particles.
solid, liquid, gas
Which best describes the particles in a solid?
vibrating in place
sublimation
Apply Boyle's law to explain what would happen to a gas if the volume of its container decreased and its temperature stayed the same.
If the volume of the container decreased at constant temp, the gas pressure would increase.
