Test on Temperature, Heat, and Thermal Energy

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). It occurs when warmer, less dense areas of a fluid rise, while cooler, denser areas sink, creating a circulation pattern.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy is never created or destroyed; it only changes form.

Front

What is heat?

Back

Heat is a form of energy that is transferred between objects due to a temperature difference.

Front

What is temperature?

Back

Temperature is a measure of how hot or cold an object is, indicating the average kinetic energy of its particles.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of all the particles in an object, related to its temperature.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials, where heat moves from the hotter object to the cooler one.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation, which can occur in a vacuum.

Front

What is an example of heat gain?

Back

An example of heat gain is ice cream melting under the sun.

Front

What is an example of heat loss?

Back

An example of heat loss is a hot bowl of soup becoming room temperature.

Front

What is the difference between heat and temperature?

Back

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