Question 965: Thermodynamics & KTG

Question

In the given (V $$-$$ T) diagram, what is the relation between pressure P
1
and P
2
?

Accepted Answer

According to ideal gas equation PV = nRT
$$ \Rightarrow V = {{nRT} \over P}$$
For an isobaric process, P = constant and V $$ \propto $$ T
Therefore, V Ã¢ÂÂ T graph is a straight line passing through origin. Slope of this line is inversely proportional to P.
In the given figure,
(Slope)
2
> (Slope)
1
$$ 	herefore $$ P
