Pressure and Temperature

Front

What happens to pressure when the volume of a container decreases?

Back

Pressure increases as the volume decreases, according to Boyle's Law.

Front

What is the definition of temperature?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance.

Front

True or False: Matter is made up of motionless particles.

Back

False. Matter is made up of particles that are always in motion.

Front

What state of matter is characterized by a definite shape and volume?

Back

Solid.

Front

What state of matter has a definite volume but takes the shape of its container?

Back

Liquid.

Front

What state of matter has neither a definite shape nor a definite volume?

Back

Gas.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of all the particles in a substance.

Front

What happens to particles in a substance when it freezes?

Back

The particles get closer together.

Front

What is the relationship between temperature and the state of matter?

Back

The state of matter of a material depends on its temperature.

Front

What is the effect of increasing pressure on the boiling point of a liquid?

Back

Increasing pressure raises the boiling point of a liquid.
