Use the data in the steam table(s) to answer the following: a. find the change in internal energy when 100 kg of steam at constant pressure p 0.1 mpa has its temperature reduced from 573.15 k to 373.15 k. b. find the change in internal energy when 100 kg of liquid water at constant pressure p 20 mpa has its temperature increased from 513.15 k to 573.15 k. c. what is the change in specific volume for both parts a and b above?
