Phases of Matter and Heat GT

Front

What are the phases of matter?

Back

The phases of matter are solid, liquid, gas, and plasma, which describe the physical states of a substance based on the arrangement and energy of its particles.

Front

What is the normal boiling point?

Back

The normal boiling point is the temperature at which a substance changes from a liquid to a gas at standard atmospheric pressure.

Front

What drives phase changes?

Back

Phase changes are driven by changes in temperature and pressure.

Front

What is condensation?

Back

Condensation is the process where gas turns into a liquid, usually when the gas is cooled.

Front

What is deposition?

Back

Deposition is the process where a gas changes directly into a solid without becoming a liquid first.

Front

What is the main characteristic of particles in a solid?

Back

In a solid, particles are in a fixed position and closely packed together.

Front

How does temperature affect the state of matter?

Back

Increasing temperature generally increases the energy of particles, causing solids to melt into liquids and liquids to evaporate into gases.

Front

What is the difference between heat and temperature?

Back

Heat is the total energy of all the particles in a substance, while temperature is a measure of the average energy of the particles.

Front

What happens during melting?

Back

During melting, a solid absorbs heat and changes into a liquid.

Front

What is freezing?

Back

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