Question

In , hot water rises up and cold water comes down to take its place, thus forming currents.

• A. conduction
• B. convection
• C. condensation

Answer 1

The correct option is B convection

Condensation is the conversion of matter from gas or vapour into liquid form. Convection is the process of movement of a fluid (gas or liquid) from one area to another. Warm fluid is less dense than cold fluid and hence rises up. Cold fluid then comes down to take its place, thus forming convection currents.
