Heat and Temperature

Front

What is the direction of thermal energy transfer between objects?

Back

Thermal energy moves from an object with a higher temperature to objects with a lower temperature.

Front

What type of energy transfer does a microwave use to cook food?

Back

A microwave uses radiation to cook food.

Front

Define thermal energy.

Back

Thermal energy is all the kinetic energy and potential energy of the atoms and molecules in an object.

Front

What instrument is commonly used for measuring temperature?

Back

A thermometer is used for measuring temperature.

Front

What causes a sunburn?

Back

A sunburn is caused by radiation.

Front

What is the difference between heat and temperature?

Back

Heat is the transfer of thermal energy, while temperature is a measure of the average kinetic energy of the particles in a substance.

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 or gases).

Front

What is radiation in the context of thermal energy?

Back

Radiation is the transfer of thermal energy through electromagnetic waves.

Front

How does a thermometer work?

Back

A thermometer works by using a substance that expands or contracts with temperature changes, allowing for the measurement of temperature.
