Question

An ideal mono atomic gas undergoes a cyclic process ABCA as shown in the fig. The ratio of heat absorbed during AB to the work done on the gas during BC is:

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

$Q_{AB}=n{C}_p\Delta T=\frac{nR\gamma \Delta T}{\gamma -1}\text{Here AB process is constant pressure.}$

$W_{BC}=nRTIn\frac{V_2}{V_1}\text{Here BC process is constant temperature process}$
