Question
A cylinder of fixed capacity 44.8 litre. contains a monatomic gas at standard temperature and pressure. The amount of heat required to increse the temperature of cylinder by 10∘C will be. (R = universal gas constant)
Answer: Option D
:
D
As we know 1 mol of any ideal gas at STP occupies a volume of 22.4 liters.
Hence number of moles of gas μ=44.822.4 = 2
Since the volume of cylinder is fixed,
Hence (△Q)V = μ(CV)△T=2×32R×10 = 30R(∵(CV)mono=3R2))
