Heat Transfer Conduction questions

Front

What is conduction?

Back

Conduction is the process of heat transfer through direct contact between materials, where energy moves from a higher temperature substance to a lower temperature substance.

Front

Are plastics good conductors of heat?

Back

No, plastics are not good conductors of heat; they are generally considered insulators.

Front

Which material is a better thermal conductor: glass or plastic?

Back

Glass is a better thermal conductor than plastic.

Front

What happens to molecules in your skin when you touch ice?

Back

The faster molecules from your finger strike the molecules in the ice, making them move faster, while the molecules in your skin slow down.

Front

What type of heat transfer causes water to boil?

Back

Convection is the type of heat transfer that causes water to boil.

Front

In conduction, does energy move from hot to cold or cold to hot?

Back

In conduction, energy is transferred from a higher temperature substance to a lower temperature substance.

Front

What is an insulator?

Back

An insulator is a material that does not conduct heat well, preventing the transfer of thermal energy.

Front

Give an example of a good conductor of heat.

Back

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

Front

What is the role of thermal energy in conduction?

Back

Thermal energy is the energy that is transferred during conduction, moving from warmer areas to cooler areas.

Front

How does temperature difference affect conduction?

Back

A greater temperature difference between two substances increases the rate of heat transfer through conduction.
