Questions
If 50 cal of heat is supplied to the system containing 2 mol of an ideal gas monoatomic gas at constant pressure, the rise in temperature is
detailed solution
Correct option is B
amount of heat given to gas to raise its temperature is, QP=nCPdT ; here n=number of moles;Cp=52 R=specific heat of gas at constant pressure;dT=change in temperature R is universal gas constant = 2 calorie/mole-K ⇒dT=QPnCp substitute the given values, ⇒dT=502 x 52 x R=5K=raise in temperature of gasTalk to our academic expert!
