Question
A fluid contained in a rigid tank initially at 27degrees C.Thereafter the system sits in the sun an absorbs energy as heat,until the final temperature is 77degrees C. The internal energy ofthe fluid is approximated by the following equation: U= 3T; U~kJ, T~K Determine the following: i) the work (kJ) for the process ii) the heat transfer (kJ) for the process Need help badly on both parts here!!

hi, You should be able to understandthe thermodynamics homework problem you are asking about byfollowing the steps below: i) the work (kJ) for the process is zero because W= pdV volume is constant since it is a rigidtank there fore W=0 ii) the heat transfer (kJ) for the process from first law of thermodynamics dQ= dW+dU dQ= dU dU = 3T= 3( final temperature- intial temperature) = 3(350-300)=150 kJ dQ=dU= 150 kJ i hope this helps u... ii) the heat transfer (kJ) for the process from first law of thermodynamics dQ= dW+dU dQ= dU dU = 3T= 3( final temperature- intial temperature) = 3(350-300)=150 kJ dQ=dU= 150 kJ i hope this helps u...Related Questions
