(a) Explanation Given info: The number of mol of the gas is 1.80 mol , temperature of the gas is 50 K . Formula to calculate the heat required is, Q = m C v Δ T (I) Q is the heat required to increase the temperature m is the mass of the gas C v is the molar heat capacity at constant volume of gas Δ T is the change in temperature of the gas For diatomic gases the molar heat capacity is, C v = 5 2 R R is the gas constant Substitute 8.314 J/mol ⋅ K for R . C v = 5 2 ( 8.314 J/mol ⋅ K ) = 20 (b) To determine The heat required to raise the temperature of monatomic gas.
