Question

The figures given below shown different processes for a given amount for an ideal gas. $\Delta$ W is work done by the system and $\Delta$ Q is heat absorbed by the system.



$\begin{array}{cccc}& ColumnI& & ColumnII\\ \left(a\right)& InFig\left(i\right)& \left(p\right)& \Delta Q>0\\ \left(b\right)& InFig\left(ii\right)& \left(q\right)& \Delta W<0\\ \left(c\right)& InFig\left(iii\right)& \left(r\right)& \Delta Q<0\\ \left(d\right)& InFig\left(iv\right)& \left(s\right)& \Delta W>0\end{array}$

• A. a $\to$ r, p b $\to$ q, s c $\to$ r, s d $\to$ q, s
• B. a $\to$ p, q b $\to$ s c $\to$ q, s d $\to$ r, p
• C. a $\to$ r, s b $\to$ q, r c $\to$ p, q d $\to$ q, s
• D. a $\to$ q,r b $\to$ r,s c $\to$ p,s d $\to$ q,r

Answer 1

The correct option is D a $\to$ q,r b $\to$ r,s c $\to$ p,s d $\to$ q,r

a-q,r b-r,s c-p,s d-q,r
