Heat and Thermodynamics
Work out the following problems. Be sure to show your work in detail. See the "Module 5 Handout" for examples of how the problems should be solved and presented.
1. How much energy (in J) is required to raise the temperature of 500 g of water from 20 to 100C, and then turn it to steam at 100C? Variables: m = 500g = 0.5 Kg Increase in water temperature, ∆T = 100-20= 800C Latent heat at 1000C, Lv =2260 KJ/Kg Specific heat capacity of water, c = 4.185 kJ/Kg/0C ∆Q = ? Relationships: ∆Q = m(c∆ ...
