Transferring heat from one object to another is called convection.

Transferring heat from one object to another is called convection.

• A. Conduction
• B. True
• C. False
• D. Radiation

Answer: (B)

Heat transfer happens in three main ways: conduction, convection, and radiation. Convection is heat transfer caused by the bulk movement of a fluid. Transferring heat from one object to another is not limited to convection; it depends on the mechanism. If two objects touch, energy moves through the solid by conduction. If energy travels through space, like sunlight warming the Earth, that's radiation. If warm fluid moves and carries heat with it, that's convection. Because convection describes heat transfer via moving fluids rather than heat transfer in general, the statement is false.
