Question 443: Thermodynamics & KTG

Question

When heat Q is supplied to a diatomic gas of rigid molecules, at constant volume its temperature increases by
$$\Delta $$T. the heat required to produce the same change in temperature, at a constant pressure is :

Accepted Answer

Heat supplied at constant volume
Q = nC
V
$$\Delta $$T
and heat supplied at constant pressure
Q' = nC
P
$$\Delta $$T
$$Q' = {{{C_P}} \over {{C_V}}}Q = \left( {1 + {2 \over 5}} \right)Q = {7 \over 5}Q$$

Answer

$${7 \over 5}Q$$

Answer

$${3 \over 2}Q$$

Answer

$${2 \over 3}Q$$

Answer

$${5 \over 3}Q$$
