Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials. It occurs when heat moves from a hotter object to a cooler one.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids or gases). It occurs when warmer parts of a fluid rise and cooler parts sink.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves. It does not require a medium and can occur in a vacuum.

Front

What happens to thermal energy when two objects at different temperatures are in contact?

Back

Thermal energy passes from the warmer object to the cooler object until they reach thermal equilibrium.

Front

What is a homogeneous mixture?

Back

A homogeneous mixture is a mixture that has a uniform composition throughout. The individual components are not distinguishable.

Front

What is a heterogeneous mixture?

Back

A heterogeneous mixture is a mixture where the individual components can be seen and are not uniformly distributed.

Front

What is the process of boiling/evaporation?

Back

Boiling/evaporation is the process of turning a liquid into vapor by heating it. It is used to separate a soluble solid from a liquid.

Front

What does 'heating' refer to?

Back

Heating refers to the process of increasing the temperature of an object or substance.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature and no heat flows between them.

Front

What is the difference between heat and temperature?

Back

Heat is the energy transferred between objects due to a temperature difference, while temperature is a measure of the average kinetic energy of the particles in a substance.
