Conductors and Insulators

Front

What is the process of heat transfer that occurs without direct contact between objects?

Back

Radiation is the process of heat transfer that occurs without direct contact between objects.

Front

How does laying on the ground help animals cool down on hot days?

Back

Heat from the animal's body is transferred to the ground, lowering the animal's body temperature.

Front

What type of material is a tin can classified as in terms of heat transfer?

Back

A tin can is classified as a conductor.

Front

What is a key characteristic of materials that are used for insulation in buildings?

Back

Insulating materials are poor conductors of heat.

Front

In which direction does heat flow between substances?

Back

Heat always flows from the warmer substance to the cooler substance.

Front

Define a conductor in the context of heat transfer.

Back

A conductor is a material that allows heat to flow through it easily.

Front

Define an insulator in the context of heat transfer.

Back

An insulator is a material that resists the flow of heat.

Front

What is an example of a good conductor of heat?

Back

Metals, such as copper and aluminum, are good conductors of heat.

Front

What is an example of a good insulator?

Back

Materials like rubber, glass wool, and Styrofoam are good insulators.

Front

What happens to the temperature of an object when it loses heat to its surroundings?

Back

The temperature of the object decreases when it loses heat to its surroundings.
