PS.5.1.3 — Effects of Heat

Front

What can heating or cooling do to a material?

Back

It can change its state, size, or temperature, but not always its substance.

Front

Give an example of a material that expands when heated.

Back

Metal expands when heated, like train tracks in the summer.

Front

What happens to most materials when they are cooled?

Back

They contract (shrink) and their particles move more slowly.

Front

What are conductors of heat?

Back

Materials that allow heat to pass through easily—like metal.

Front

What are insulators of heat?

Back

Materials that do not allow heat to pass through easily—like wood, plastic, and silicone.

Front

Why do changes often happen faster at higher temperatures?

Back

Heat gives particles more energy, making changes occur more quickly.

Front

Examples of conductors

Back

metals like silver, copper, gold, aluminum, and steel

Front

Examples of insulators

Back

plastic, wood, rubber, glass, air, porcelain, styrofoam, dry paper, and dry cotton.
