What is thermal equilibrium?

Back

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

What is the difference between renewable and non-renewable energy sources?

Back

Renewable energy sources can be replenished naturally (e.g., solar, wind), while non-renewable sources cannot (e.g., fossil fuels, nuclear).

Front

What is an example of convection in everyday life?

Back

A hot air balloon rising is an example of convection, as warm air inside the balloon causes it to rise.
