You decide to take a nice hot bath but discover that your thoughtless roommate has used up most of the hot water. You fill the tub with 270 kg of 30.0°C water and attempt to warm it further by pouring in 5.00 kg of boiling water from the stove.
(a) Is this a reversible or an irreversible process? Use physical reasoning to explain.
(b) Calculate the final temperature of the bath water.
(c) Calculate the net change in entropy of the system (bath water + boiling water), assuming no heat exchange with the air or the tub itself.
This looks like a duplicate post. Look for the answer in the thread of one of your other posts.
We did not find results for: a typical woman gives off heat at rate of about 8000 calories per hour. how long would a woman have to stay in a bath of 60L (60,000 g) of 26 C water in order to raise the water temperature to 30 c ? presure that all the heat given off by the woman is transferred to the water , and that the water does not lose any heat to the air. show your calculations..
