One mole of an ideal gas requires 207 J heat to raise the temperature by 10 K when heated at constant pressure. If the same gas is heated at constant volume to raise the temperature by 5 K, then the heat required may be

Options:

Answer:

Solution:

$C_{P} = \frac{207}{10} = 20.7 J / K \approx \frac{5}{2} R$ (monoatomic), so $C_{V} = C_{P} - R = 12.4 J / K$ .

$Q = C_{V} \times 5 = 62.1 J .$
