Heat always flows from a body having more thermal energy to another having less thermal energy. Is it true or false? Give reason.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Statement**: The statement claims that heat always flows from a body with more thermal energy to one with less thermal energy. We need to analyze this statement to determine its truthfulness.

2. **Defining Thermal Energy and Temperature**: Thermal energy is the total internal energy of a system due to the kinetic energy of its molecules. Temperature is a measure of the average kinetic energy of the particles in a substance. A body with higher thermal energy typically has a higher temperature.

3. **Heat Transfer Direction**: Heat transfer occurs from a region of higher temperature (or thermal energy) to a region of lower temperature. This is based on the second law of thermodynamics, which states that heat naturally flows from hot to cold bodies until thermal equilibrium is reached.
