If \[\gamma \] denotes the ratio of two specific heats of a gas, the ratio of slopes of adiabatic and isothermal PV curves at their point of intersection is [NCERT 1990; MH CET 1999; MP PMT 2000]
A) \[1/\gamma \]
B) \[\gamma \]
C) \[\gamma -1\]
D) \[\gamma +1\]
Correct Answer:
B
Solution :
Slope of adiabatic curve = g ´ (Slope of isothermal curve)
