Question

the process by which heat moves through air or liquid is called ______. choose one option a boiling b conduction c convection d temperature

Explanation:

• Option A: Boiling is a phase change (liquid to gas) when a substance reaches its boiling point, not heat transfer through air/liquid.
• Option B: Conduction is heat transfer through direct contact of particles (e.g., in solids), not through air/liquid flow.
• Option C: Convection is heat transfer via the movement of fluids (liquids or gases), which matches the description of heat moving through air or liquid.
• Option D: Temperature is a measure of thermal energy, not a heat transfer process.

Answer:

C. convection
