NEET Physics Kinetic Theory of Gases Questions Solved


70 calories of heat is required to raise the temperature of 2 moles of an ideal gas at constant pressure from 30°C to 35°C. The amount of heat required to raise the temperature of same gas through the same range (30°C to 35°C) at constant volume (R = 2 cal/mol/K)

1.  30 cal                       

2.  50 cal

3.  70 cal                       

4.  90 cal

2.    QP=μCPT        2×CP×35-30         CP=7calmoleK             CP-CV=R         CV=CP-R=7-2 =5 calmolekevin         QV=μCVT=2×5×35-30 =50 cal.
