What is geothermal energy and how does it affect water molecules in geothermal power plants?

Back

Geothermal energy is heat from the Earth. In geothermal power plants, it increases the energy of water molecules as they are heated underground.

Why does a larger container of applesauce remain cooler than a smaller container after heat transfer?

Back

The larger container remains cooler because the energy transferred to it is spread out over more molecules.

How does the temperature of two cards compare before they touch, and what happens after they touch?

Back

Before touching, the top card is hotter than the bottom card. After touching, kinetic energy is transferred until both cards reach the same temperature.

What is the relationship between the size of a cup and its temperature after heat transfer?

Back

A larger cup will be cooler than a smaller cup after heat transfer because the energy is spread out over more molecules.

What is kinetic energy and how does it relate to temperature?

Back

Kinetic energy is the energy of motion. As temperature increases, the kinetic energy of molecules also increases.

Explain the concept of heat transfer.

Back

Heat transfer is the process of thermal energy moving from a hotter object to a cooler one until thermal equilibrium is reached.

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

How does the size of an object affect its ability to retain heat?

Back

Larger objects can retain heat longer because the energy is distributed over more molecules, leading to a slower temperature change.
