Heat and Energy ,[object Object],[object Object],[object Object],Section 2  Defining Heat Chapter  9
Transfer of Particles’ Kinetic Energy as Heat Chapter  9 Section 2  Defining Heat Energy is transferred as heat from the higher-energy particles to the lower-energy particles, as shown on the left. The net energy transferred is zero when thermal equilibrium is reached, as shown on the right.

Convection, Conduction, and Radiation Chapter  9 Section 2  Defining Heat
Conservation of Energy ,[object Object],[object Object],Section 2  Defining Heat Chapter  9 CONSERVATION OF ENERGY  PE  +   KE  +   U  = 0 the change in potential energy + the change in kinetic energy + the change in internal energy = 0
Conservation of Energy Chapter  9 Section 2  Defining Heat
Sample Problem ,[object Object],Section 2  Defining Heat Chapter  9 An arrangement similar to the one used to demonstrate energy conservation is shown in the figure. A vessel contains water. Paddles that are propelled by falling masses turn in the water. This agitation warms the water and increases its internal energy. The temperature of the water is then measured, giving an indication of the water’s internal energy increase.
Sample Problem,  continued ,[object Object],Section 2  Defining Heat Chapter  9 If a total mass of 11.5 kg falls 1.3 m and all of the mechanical energy is converted to internal energy, by how much will the internal energy of the water increase? (Assume no energy is transferred as heat out of the vessel to the surroundings or from the surroundings to the vessel’s interior.)
Sample Problem,  continued ,[object Object],[object Object],[object Object],[object Object],[object Object],Section 2  Defining Heat Chapter  9 Unknown:   U  = ?
