Question

If \(C_v\) is the specific heat capacity at constant volume of a gas, then the amount of heat required to increase the temperature of 2 moles of the gas from \(27^\circ\text{C}\) to \(127^\circ\text{C}\) at constant volume is

• A. \(100 C_v\)
• B. \(50 C_v\)
• C. \(500 C_v\)
• D. \(300 C_v\)
• E. \(200 C_v\)

Hint:

Always remember that \(\Delta T\) in degrees Celsius is equal to \(\Delta T\) in Kelvin. You don't need to add 273 to both and then subtract; just subtract the Celsius values directly.
