if there are two diabatic expansions of gases A and B and slope of their P/V curve are in this way: slopeA> slopeB then

which gas is monoatomic and which is diatomic?

If you plot the PV graph of an adiabatic expansion, is the slope negative or positive?

What is the relationship between P and V during an adiabatic change (hint: it involves [itex]\gamma = C_p/C_v[/itex]).

What is dP/dV (slope) of this graph at a given point? (hint: think derivative, dP/dV of the graph).
