Question

The specific heat of helium at constant volume is 12.6 Jmol ⁻¹ ~K ⁻¹ . The specific heat of helium at constant pressure in Jmol ⁻¹ ~K ⁻¹ is about (Assume the temperature of the gas is moderate, universal gas constant, R=8.314 Jmol ⁻¹ ~K ⁻¹ )

Quantrex Academy · Accepted Answer

Correct answer: D. 21

As C_V=12.6 ~J ~mol ⁻¹ ~K ⁻¹ is given in SI unit So, R=8314 ~J ~mol ⁻¹ ~K ⁻¹ Then, C_p=C_V+R=12.6+8.314=21

The specific heat of helium at constant volume is 12.6 Jmol ⁻¹ ~K ⁻¹ . The specific heat of helium at constant pressure in Jmol ⁻¹ ~K ⁻¹ is about (Assume the temperature of the gas is moderate, universal gas constant, R=8.314 Jmol ⁻¹ ~K ⁻¹ )
