Problem

At a given state

(P,V)

of an ideal gas, let

m_{i}

be the magnitude of the slope

(dP/dV)

of the isothermal curve and

m_{a}

be that of the adiabatic curve through the same point. For a mono-atomic ideal gas with

\gamma =1.67

, the ratio

m_{a}/m_{i}

is (a)

1.00

(b)

1.67

(c)

0.60

(d)

2.67
