Thermal Energy

Front

What happens to heat energy when a warm object touches a cooler object?

Back

Heat energy flows from the warmer object to the cooler object.

Front

What is the process called when heat is transferred through the movement of fluids (liquids or gases)?

Back

Convection.

Front

In which direction does heat transfer occur?

Back

From an area of high temperature to an area of low temperature.

Front

What is the term for the transfer of heat through direct contact between materials?

Back

Conduction.

Front

How does heat transfer occur in solids?

Back

Through conduction, as energy is conducted from atom to atom.

Front

What is thermal equilibrium?

Back

A state where two objects in contact reach the same temperature and no heat flows between them.

Front

What is the primary method of heat transfer in liquids and gases?

Back

Convection.

Front

What is the role of thermal conductivity in heat transfer?

Back

It measures how well a material conducts heat; higher thermal conductivity means better heat transfer.

Front

What is the difference between conduction and convection?

Back

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

Front

What happens to the temperature of an object when it absorbs heat?

Back

The temperature of the object increases.
