Three samples of 100 g of water (samples I, II and III), initially kept at 1 atm pressure and 298 K were given the following treatments. Sample I was heated to 320 K and cooled to 298 K
Sample II was heated to 300 K, cooled to 273 K and heated to 298 K
Sample III was heated to 373 K and cooled to 298 K
At the end of these processes, the internal energy of
Text Solution
Verified by ExpertsThe correct answer is:
D
I, II and III are the same
As Internal energy change is a state function so it depends only on the initial and final temperature and does not depends on the path taken.
