The kinetic molecular theory says that all matter is made of _______ ________.
Thermal energy is the sum of what?
Potential and kinetic energy
What is held constant in the relationship described by Boyle's Law?
Temperature
What is pressure?
the amount of force exerted per unit of area.
The relationship between volume and temperature is described by who's law?
Charles's
What type of matter had no definite shape and no definite volume?
gas
What happens to particles as kinetic energy increases?
The particles move faster.
Particles are in constant, _______ motion.
random
What is the constant in the relationship described by Charle's Law?
Pressure
What happens to the pressure when a sample of gas increases?
It decreases.
What happens to energy when particles collide?
It is not lost.
What type of matter has a definite volume, but no definite shape?
Liquid
What is the sum of potential and kinetic energy called?
thermal energy
Gas behavior is affected by what change?
Temperature change
When the temperature increases, the ______ of gas particles also increases.
volume
As an example of Charle's Law, when a balloon cools, what happens to it's volume?
It decreases
What happens to collisions when the volume of a gas increases?
There are fewer collisions.
What is the result of particles' colliding with their container?
Pressure
What type of matter has a definite shape and a definite volume?
solid
What is the theoretical lowest possible temperature of matter?
Absolute zero
What happens when the volume of a sample of gas decreases?
Pressure increases
What did Boyle's Law state there was a relationship between?
pressure and the volume of gas
What does Charles' Law state?
The volume of gas increases with increasing temperature if the pressure is constant.
What does Boyle's Law state?
When either volume or pressure increases, the other property decreases, when temperature is constant
What do scientist's theorize about particles at absolute zero?
That the particles do not move.
