The amount of heat energy required to raise the temperature of 1 g of Helium at NTP, from T1K to T2K is
34NakBT2−T1
34NakBT2T1
38NakBT2−T1
32NakBT2−T1
As here volume of the gas remains constant, therefore the amount of heat energy required to raise the temperature of the gas is ΔQ=nCvΔT
Here, Number of moles, n=14
CV=32R ∵ He is a monatomic ΔT=T2−T1 ∴ ΔQ=1432RT2−T1 =38NakBT2−T1 ∵kB=RNa
