Question

A gas park in two processes in which it is hcated from the same initial state 1 to the same final temperature. The processes are shown on the P - V diagram by the straight lines $1-3$ and $1-2$. $2$ and $3$ are the points on the same isothermal curve. $Q_1$ and $Q_2$ are the heat transfer along the two processes. Then

• A. $Q_1=Q_2$
• B. $Q_1<Q_2$
• C. $Q_1>Q_2$
• D. Insufficient data

Answer 1

The correct option is C $Q_1>Q_2$

here temperature will be same at point $2$ and $3$
now we see from the curve that heat will be transfer from point $1$ to $2$ and $3$ respectively,
hence $Q=C_{v}dT$, but it is not important that if temperature will increase "$Q$" will also increse
hence $Q_1>Q_2$ it transfer heat from point $1$ to $2$
