Matter can change from one state to another by heating or cooling.

​

When matter changes state, it does not change what it is.

​How does heating cause matter to change state?

​

Multiple Choice

When Chocolate is in the solid state and melts it is still chocolate. It is now just in the liquid state.

• True

• False

An Increase in the amount of heat.

​

Sometimes a lot of heat is needed to melt a solid.

​

If you add heat to a liquid, it becomes a gas.

​Heating

Multiple Choice

Heating is

• An increase in the amount of heat

• A decrease in the amount of heat

• When liquid turns into a gas

Multiple Choice

Water Vapor

• The Gas from a liquid

• A decrease in the amount of heat.

• The gas from a solid

When liquid turns into a gas by adding heat.​

​

The increase in heat causes the particles to move farther apart. ​

​Evaporation

​

Multiple Choice

Evaporation

• The heat

  increases

• The heat decreases

• When water cools.

• The gas turns into a liquid.

​

Decrease in temperature; getting colder.

​

When liquid cools, the particles pack closer together.

​

Turning into a solid.

​Cooling

​

​When a gas becomes a liquid by decreasing the temperature.

​

The particles pack closer together.

​

The water on the glass came from the air.

Water vapor in the air touched the side of the cold glass.

When it did, the gas particles slowed down.

The water vapor changed into a drop of liquid water.
