Thermal Energy (Amplify)

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of the particles in a substance, which determines its temperature.

Front

What is the coldest temperature among these options: -13°C, -109°C, 0°C, 13°C?

Back

-109°C is the coldest temperature.

Front

What does it mean that energy can't be created or destroyed?

Back

This means that energy can only change forms; it cannot be made or eliminated.

Front

What is the definition of 'average'?

Back

A number that describes a set of data and can be calculated by adding all the numbers in a list and then dividing by the number of numbers.

Front

What is kinetic energy?

Back

Kinetic energy is the energy that an object has because it is moving.

Front

What is equilibrium in a thermal system?

Back

Equilibrium is the stable state reached when the molecules of a system transfer energy evenly.

Front

What is the relationship between temperature and thermal energy?

Back

As temperature increases, the thermal energy of the substance also increases.

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids and gases).

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as sunlight.
