Heat Transfer

Front

What is heat transfer?

Back

Heat transfer is the movement of thermal energy from one object or substance to another due to a temperature difference.

Front

Define conduction in the context of heat transfer.

Back

Conduction is the process of heat transfer through direct contact between materials, where heat moves from the hotter object to the cooler one.

What is convection?

Back

Convection is the transfer of heat through fluids (liquids and gases) caused by the movement of the fluid itself, often due to differences in temperature and density.

Explain radiation as a mode of heat transfer.

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation, which can occur in a vacuum.

How does a hot air balloon float?

Back

A hot air balloon floats because the heated air inside the balloon expands, making it less dense than the cooler air outside, resulting in buoyancy.

What is an example of heat transfer by conduction?

Back

An example of heat transfer by conduction is an ice cube melting in a person's hand.

Front

Why do you need a pot holder when handling a hot metal pot?

Back

You need a pot holder because conduction causes the metal pot to become hot, and touching it directly can cause burns.

Front

What is the primary way heat travels through liquids and gases?

Back

The primary way heat travels through liquids and gases is through convection.

Front

What happens to the temperature of an ice cube when it is placed on a warm surface?

Back

The temperature of the ice cube increases as it absorbs heat from the warm surface, causing it to melt.
