One mole of an ideal gas $(C_{V} = 20 J K^{- 1} {mol}^{- 1})$ initially at STP is heated at constant volume to twice the initial temperature. For the process, W and q will be

Options:

Answer:

Solution:

One mole of an ideal gas initially at STP is heated at constant volume to twice the initial temperature, Therefore

$W = -P ∆ V = -P \times 0 = 0$

$Q = C_{v} (∆ T) = 20 \times 273 = 5460 J = 5.46 k J$
