Question

Which single property decides the direction of the flow of heat?

Answer 1

1. Heat capacity is the amount of heat needed to raise the temperature of a body by unity.
2. It is given by: $C^{\text{'}}=\frac{∆Q}{∆T}$where $∆Q$ is the heat absorbed or rejected, $∆T$ is the change in temperature
3. Heat energy is the energy that is transferred from a hot object to a cold object.
4. So when two bodies are connected with each other, a change in temperature is the property that decides the direction of the flow of heat.
