Question:

A gas can be taken from $A$ to $B$ via two different processes ACB and ADB.

When path $A C B$ is used $60 \mathrm{~J}$ of heat flows into the system and $30 \mathrm{~J}$ of work is done by the system. If path ADB is used work done by the system is $10 \mathrm{~J}$. The heat Flow into the system in path ADB is :

1. $40 \mathrm{~J}$

2. $80 \mathrm{~J}$

3. $100 \mathrm{~J}$

4. $20 \mathrm{~J}$
