Thermal Energy and Heat Flashcard

Front

What is thermal energy?

Back

The sum of the kinetic energy and the potential energy of all the particles that make up an object.

Front

What device is used to determine the specific heat of a substance?

Back

Calorimeter.

Front

Which substance is commonly used as a coolant?

Back

Water.

Front

Why does water have a high specific heat?

Back

Due to strong hydrogen bonds allowing effective heat absorption.

Front

What is heat?

Back

Thermal energy that flows from something at a higher temperature to something at a lower temperature.

Front

What is specific heat?

Back

The amount of heat required to raise the temperature of 1 gram of a substance by 1 degree Celsius.

Front

What is the relationship between temperature and thermal energy?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance, while thermal energy is the total energy of all particles.

Front

What is conduction?

Back

The transfer of heat through direct contact between materials.

Front

What is convection?

Back

The transfer of heat through the movement of fluids (liquids or gases).

Front

What is radiation?

Back

The transfer of heat through electromagnetic waves, such as sunlight.
