Find the specific heat (in J/mole K) of a gas kept at constant volume when it takes 1.0 *104 J of heat to raise the temperature of 5.0 moles of the gas 200 K above the initial temperature.

Question

Quizplus · Accepted Answer

The specific heat (Cv) of the gas at constant volume can be calculated using the formula:

ΔQ = nCvΔT

where ΔQ = 1.0 x 10^4 J (given), n = 5.0 moles (given), ΔT = 200 K (given)

Solving for Cv, we get:

Cv = ΔQ/nΔT
Cv = (1.0 x 10^4 J)/(5.0 moles x 200 K)
Cv = 10 J/mole K

Therefore, the specific heat of the gas kept at constant volume is 10 J/mole K, which is choice C.
