24-25 Energy Study Guide

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, typically occurring in solids.

Front

What happens to the temperature of water when it is left in a room for a period of time?

Back

The temperature of the water will tend to equalize with the room temperature due to heat transfer.

Front

What is solar energy?

Back

Solar energy is the energy that comes from the sun, which can be converted into heat or electricity.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically related to its height.

Front

What is the energy transformation that occurs when a fire warms your hands?

Back

Chemical energy is converted into heat energy.

Front

What is heat energy?

Back

Heat energy is the energy that comes from the temperature of matter; it is the energy transferred between objects due to a temperature difference.

Front

What is the role of aluminum foil in a solar oven?

Back

Aluminum foil reflects sunlight into the oven, helping to trap heat and cook the food inside.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature and no heat flows between them.

Front

What is the difference between heat and temperature?

Back

Heat is the total energy of molecular motion in a substance, while temperature is a measure of the average energy of that motion.

Front

What is an example of energy transformation in cooking?

Back

In cooking, electrical energy from a stove is transformed into heat energy to cook food.
