Solution: The temperature of the mixture will be between 30°C and 50°C because hot water loses heat and simultaneously cold water gains heat. This keeps the temperature in between 30°C and 50°C. 9. An iron ball at 40°C is dropped in a mug containing water at 40°C. The heat will. (a) flow from the iron ball to water.

heat, energy that is transferred from one body to another as the result of a difference in temperature. If two bodies at different temperatures are brought together, energy is transferred—i.e., heat flows—from the hotter body to the colder. The effect of this transfer of energy usually, but not always, is an increase in the temperature of

Thermal energy refers to the kinetic energy of the particles in a substance. Objects in thermal contact of differing temperatures will transfer energy (heat to the cooler substance) and reach thermal equilibrium. This process is called heat transfer. Conduction, convection and radiation are methods of heat transfer.
