FLASHCARD: Reading Pkt: What Is Heat?

Front

What happens when you put a cold metal spoon in a bowl of hot soup?

Back

The spoon warms up.

Front

What is heat?

Back

The energy that moves between objects at different temperatures.

Front

What effect is caused by the atmosphere trapping energy?

Back

Greenhouse effect.

Front

What are the three ways that thermal energy moves from one object to another?

Back

Conduction, convection, and radiation.

Front

What occurs when two objects reach the same temperature?

Back

Energy transfer stops.

Front

Define conduction in the context of heat transfer.

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

Define convection in the context of heat transfer.

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids or gases).

Front

Define radiation in the context of heat transfer.

Back

Radiation is the transfer of energy through electromagnetic waves, such as heat from the sun.

Front

What is thermal equilibrium?

Back

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

Front

How does the greenhouse effect impact Earth's temperature?

Back

The greenhouse effect traps heat in the atmosphere, leading to an increase in Earth's average temperature.
