4.48 L of an ideal gas at STP requires 12 cal to raise the temperature by 15^(0)C at constant volume. The C_(P) of the gas is ____ cal

4.48 L of an ideal gas at STP requires 12 cal to raise the temperature

1.	4.48 L of an ideal gas at STP requires 12 cal to raise the temperature by 15^(0)C at constant volume. The C_(P) of the gas is ____ cal
Answer» <P> SOLUTION :At constant volume heat released `= nC_(V)dT` So `12 = (4.48)/(22.4) xx C_(v) xx 15, C_(v) = 4` cal/mole We know that `C_(p) C_(V) + R = 4 + 2 = 6` cal/mole
