Front

What is the definition of a liquid?

Back

A liquid has a definite volume but an indefinite shape.

Front

What happens to the particles of a liquid?

Back

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

Front

What is the effect of adding heat to a closed system?

Back

Adding heat to a closed system can cause a change in the state of matter.

Front

What phase change occurs when heat is added between solid and liquid?

Back

Melting occurs when heat is added between solid and liquid.

Front

What happens to particles when thermal energy is supplied?

Back

Particles speed up when more thermal energy is supplied.

Front

What is the difference between solids, liquids, and gases in terms of particle arrangement?

Back

Solids have closely packed particles, liquids have loosely packed particles that can move around, and gases have widely spaced particles that move freely.

Front

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

Back

The term for the change from liquid to gas is evaporation.

Front

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

Back

The term for the change from gas to liquid is condensation.

Front

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

Back

Temperature affects the energy of particles, which can lead to changes in state (e.g., solid to liquid, liquid to gas).

Front

What is the definition of thermal energy?

Back

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