Front

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 (e.g., coal, oil) are finite.

Front

What is conduction in terms of heat transfer?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is the role of neutrons in an atom?

Back

Neutrons help stabilize the nucleus of an atom and contribute to its mass.
