Chapter 13

Chapter 13. Heat Energy and Its Effects. Heat Transfer. When two objects A and B of different temperatures (T A >T B ) are placed in thermal contact, the temperature of the warmer decreases and the temperature of the cooler increases Heat flow (transfer) from object A to Object B.

THE QUANTITY OF HEAT The thermal energy lost or gained by objects is called heat.

THE QUANTITY OF HEAT The thermal energy lost or gained by objects is called heat. One calorie (cal) is the quantity of heat required to change the temperature of one gram of water through one Celsius degree. The mechanical equivalent of heat is given by: 1 cal = 4.186 J.
