Question

A gas expands from a volume of 3.0dm3 to 5.0dm3 against a constant external pressure of 3.0 atm. The work done during of temperature 290.0 K. Calculate the final temperature of water (specific heat of water=4.184Jg1K1)

Open in App
Solution

WPV=PΔV=3(53)=6
Latm=6×101.325=607.95J
Molar heat capacity of water
=4.184×18=75.312J/mol
Now, Q=msΔT
or ΔT=Qms=607.95(10×75.312)=0.807
Final temperature =290+0.807=290.807K
We get, 290.807K
