Homework Answers
First , when heat is added at constant temperature. Second, when heat is added at constant pressure. In both situations, final temperature would be different despite mass , initial temperature and heat addition is same because specific heat at constant temperature and at constant pressure are different.

Which statement is wrong? 1. Adding the same amount of heat to two A different objects will produce the same in- in crease in temperature. T 2. Temperature measures the average ki- netic energy of random motion, but not other kinds of energy. 3. Different substances have different ther- A mal properties due to differences in the way 11 energy is stored internally in the substances. 4. When the same amount of heat produces different changes in temperature in two...

Two containers of the same gas each holding the same amount of mass, initially at temperature T1 and T2 are brought into thermal equilibrium Assuming no heat loss to the atmosphere and constant container volumes calculate (neglect the mass of the containers): 1) The final temperature of the gas in each container 2) The change of internal energy 3) The change of entropy For this process- if: A) The containers are placed in thermal contact. B) A reversible cycle works...
