question 88

Multiple Choice

On a PV diagram,2 curves are plotted,both starting at the same point (P₁,V₁) and both ending at the same increased volume (V₂) .One curve is for an isothermal process;the other is for an adiabatic process.Except for the common starting point,which curve is the upper one?

• A)The isothermal process curve will always be the upper one.
• B)The adiabatic process curve will always be the upper one.
• C)Since they start at the same point and end at the same volume,they will coincide.
• D)The isothermal one will start out higher,but the adiabatic one will eventually cross it.
