Question

Heat flows as a result of difference in

• A. masses
• B. weights
• C. temperatures
• D. none of these

Answer 1

The correct option is C

temperatures

1. Heat energy flows only from a hotter to a cooler body.
2. This flow of heat continues until the temperatures of both the bodies become the same. In this state, bodies are said to be in ‘thermal equilibrium.
3. When the state of thermal equilibrium is attained, no further flow of heat is possible.
4. So, heat flows as a result of the difference in temperatures.

Hence, C) is the correct option.
