What is heat energy?

Back

Heat energy is a form of energy that is transferred between objects due to a temperature difference. It flows from warmer objects to cooler ones.

What is an insulator?

Back

An insulator is a material that does not conduct heat well. Examples include rubber, glass, and pot holders.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. For example, when a metal spoon is heated in a pot of hot soup.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). Warm fluid rises while cooler fluid sinks, creating a circulation.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves. An example is the heat from the sun reaching the Earth.

What happens when you touch a cold object?

Back

When you touch a cold object, heat transfers from your hand to the object, making your hand feel cold.

Front

What is an example of a good conductor of heat?

Back

Metals like copper and aluminum are good conductors of heat.

Front

What is an example of a good insulator?

Back

Materials like wood, plastic, and rubber are good insulators.

Front

How does heat travel from the sun to the Earth?

Back

Heat travels from the sun to the Earth through radiation.

What is the role of pot holders?

Back

Pot holders are used to protect your hands from heat when handling hot pots and pans, as they are made of insulating materials.
