Conduction and Insulation

Front

What is conduction?

Back

Conduction is the process of heat transfer through direct contact between materials.

Front

True or False: Conduction requires direct contact between two objects.

Back

True

Front

What happens to particles in a material when it is heated?

Back

The particles increase in thermal energy, which increases their kinetic energy and causes the material to expand.

Front

What is thermal expansion?

Back

Thermal expansion is the increase in volume of a material as its temperature increases.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy can never be created or destroyed, only transformed from one form to another.

Front

What are the three energy transformations that occur when a car battery is active?

Back

Chemical energy is transformed into electrical energy, which is then transformed into light energy.

Front

What is an insulator?

Back

An insulator is a material that does not conduct heat or electricity well.

Front

Give an example of a good insulator.

Back

Wood is an example of a good insulator.

Front

What is the role of insulation in buildings?

Back

Insulation helps to reduce heat transfer, keeping buildings warm in winter and cool in summer.

Front

What is the difference between conduction and convection?

Back

Conduction is heat transfer through direct contact, while convection is heat transfer through the movement of fluids.
