Materials under the application of heat
Changing Phases
When heat is applied to materials they undergo changes. They may
change into different states- solid, liquid, or gas.
Heating materials can cause materials to change
Example:
• A slab of butter left lying in the sun will melt.
• When ice is warmed it changes into water.
• When you heat water, tiny droplets of water leave the container and
enter the air. These tiny droplets are called water vapor. This process is called
evaporation and is part of the water cycle.

Let’s Do More
1. What happened to the ice when heated? Why?
Turned into liquid.
2. Is there a change in the appearance of the ice?
As liquid water is heated, it evaporates into water vapor.
3. What change took place?
The change from the solid state to the liquid state is called melting.
4. Describe the changes in the properties of the ice that took place when
heated.
Application of heat to ice causes only physical changes in which no
substances are formed.
5. How did you feel with the activity?
I find the activity engaging.
