KMT/States of Matter/Phase Changes/Heat Transfer

Front

What is the Kinetic Molecular Theory (KMT) of gases?

Back

The Kinetic Molecular Theory explains that gas particles are in constant motion, have negligible volume, and do not attract or repel each other. The temperature of a gas is related to the average kinetic energy of its particles.

What happens to the particles in a liquid?

Back

In a liquid, particles are close together but can flow around each other, allowing liquids to take the shape of their container.

Front

What is melting?

Back

Melting is the process where a solid changes into a liquid when it absorbs heat.

Front

How do gas particles compare to solid particles in terms of distance?

Back

Gas particles are farther away from each other than solid particles.

Front

Do molecules move in a solid?

Back

Yes, molecules in a solid vibrate in place but do not move freely.

Front

What is condensation?

Back

Condensation is the process where a gas changes into a liquid, usually when it cools down.

Front

What is evaporation?

Back

Evaporation is the process where a liquid changes into a gas, usually when it absorbs heat.

Front

What is freezing?

Back

Freezing is the process where a liquid changes into a solid when it loses heat.

Front

What is the relationship between temperature and kinetic energy in gases?

Back

The temperature of a gas is directly proportional to the average kinetic energy of its particles.

Front

What is a plasma state of matter?

Back

Plasma is a state of matter where gas is energized to the point that some electrons are freed from their atoms, resulting in a mixture of charged particles.
