Final Test Thermal Energy Amplify

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials, where faster-moving molecules transfer energy to slower-moving ones.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as heat from the sun reaching the Earth.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state reached when two objects in contact have equal temperatures and no net heat transfer occurs between them.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion; in thermal terms, it relates to the speed of molecules.

Front

How does temperature affect molecular motion?

Back

As temperature increases, the average kinetic energy of molecules increases, causing them to move faster.

Front

What happens to the temperature of a hot object in a cooler environment?

Back

The hot object will lose heat to the cooler environment until thermal equilibrium is reached.

Front

What is the role of the surrounding environment in heat transfer?

Back

The surrounding environment can absorb or provide heat, affecting the temperature of objects within it.

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 molecules in a substance.

Front

What is an example of conduction in everyday life?

Back

An example of conduction is when a metal spoon gets hot after being placed in a pot of boiling water.
