What happens when heat is added to a solid?

Back

When heat is added to a solid, it can change into a liquid, a process known as melting.

Front

What is evaporation?

Back

Evaporation is the process by which liquid water turns into water vapor (gas) when heat is applied.

Front

What is condensation?

Back

Condensation is the process by which water vapor (gas) cools and changes back into liquid water.

Front

What causes ice to melt?

Back

Ice melts when heat is added, causing it to change from a solid to a liquid.

Front

What is freezing?

Back

Freezing is the process of a liquid turning into a solid when heat is removed.

Front

What is the role of temperature in changing states of matter?

Back

Temperature affects the energy of particles in a substance, which can cause changes in state, such as melting or freezing.

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water evaporates, condenses, and precipitates back to the Earth.

Front

What happens to water when it is heated?

Back

When water is heated, it can evaporate and turn into water vapor (gas).

Front

What is sublimation?

Back

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