Question 445: Thermodynamics & KTG

Question

The ratio of work done by an ideal monoatomic gas to the heat supplied to it
in an isobaric process is :

Accepted Answer

In an isobaric process,
Heat supplied, Q = n C
p
$$\Delta $$ T
Work done,  w = nR$$\Delta $$T
$$ 	herefore $$   Ratio = $${w \over Q}$$ = $${{nR\Delta T} \over {n{C_p}\Delta T}}$$
=   $${R \over {{5 \over 2}R}}$$
=   $${2 \over 5}$$
[C
p
= $${5 \over 2}$$ R for monoatomic gas]
