Kinetic molecular theory

Front

What happens to the particles of a solid when heat is added?

Back

The particles move faster.

Front

What state of matter is characterized by having a definite volume but no definite shape?

Back

Liquid.

Front

What is the relationship between the energy of particles and their movement?

Back

The more energy that particles have, the faster they move.

Front

Which state of matter generally has the least amount of energy?

Back

Solids.

Front

What properties describe a gas?

Back

Gases have no definite shape or volume and the particles are far apart and move freely.

Front

What is the kinetic molecular theory?

Back

It is a theory that explains the behavior of gases in terms of particles in motion.

Front

How do the particles in a liquid behave compared to those in a solid?

Back

Particles in a liquid are more mobile than in a solid but less mobile than in a gas.

Front

What happens to the energy of particles in a gas when temperature increases?

Back

The energy of the particles increases, causing them to move faster.

Front

What is the effect of temperature on the state of matter?

Back

Increasing temperature can change a solid to a liquid (melting) or a liquid to a gas (evaporation).

Front

What defines the shape and volume of a solid?

Back

Solids have a definite shape and volume due to closely packed particles.
