Figure 7: An iron has a hot base that transfers heat to iron the clothes. Figure 8: When your lips touch a cup of hot chocolate, the heat from the hot cup is transferred to warm your lips.
If an object has a large specific heat capacity, a large amount of heat is required to make its temperature increase by one degree Celsius. PTS: 1 TOP: Specific Heat Capacity KEY: heat | capacity

Heat Transfer Worksheet. Specific heat capacity. 1. (a) How much energy is lost when 50 g of iron cools from 45°C to 15°C? (b) Find the specific heat capacity of gold if 108 J of energy raise the temperature of 9.0 g from 0°C to 100°C. (c) Find the amount of energy required to raise the temperature of 1000 kg of sea-water through 40K. 2.
Distinguish between heat and temperature, and explain temperature using the concept of kinetic energy and the particle model of matter. Compare heat transmission in different materials (e.g., conduction of heat in different solids, absorption of radiant heat by different surfaces)
Algebraic expressions for the correction factor Fhave been developed for vari- ous shell-and-tube and cross-flow heat exchanger configurations [1–3], and the results may be represented graphically. Selected results are shown in Figures 11S.1 through 11S.4 for common heat exchanger configurations.
