States of Matter and Phase Changes

Front

What are the characteristics of particles in a liquid?

Back

Particles of a liquid are free to move around one another but still touch.

Front

How do you calculate the starting volume if the starting temperature is 30°C, the final temperature is 60°C, and the final volume is 10L?

Back

The starting volume is 5L.

Front

What is the phase change called when a solid turns into a liquid?

Back

Melting.

Front

What is the term for a repeating arrangement of particles in a solid?

Back

Crystalline.

Front

What is the process called when a solid turns directly into a gas?

Back

Sublimation.

Front

What is the phase change from liquid to solid called?

Back

Freezing.

Front

What happens to the energy of particles during melting?

Back

The energy of particles increases as they absorb heat.

Front

What is the term for the change from gas to liquid?

Back

Condensation.

Front

What is the effect of temperature on the volume of a gas?

Back

As temperature increases, the volume of a gas typically increases (Charles's Law).

Front

What is the difference between crystalline and amorphous solids?

Back

Crystalline solids have a regular, repeating arrangement of particles, while amorphous solids do not.
