MCQ

In the $p-V$ diagram below, the dashed curved line is an adiabat.For a process that is described by a straight line joining two points $X$ and $Y$ on the adiabat (solid line in the diagram) heat is (Hint consider the variation in temperature from $X$ to $Y$ along the straight line)

A
absorbed throughout from $X$ to $Y$
B
released throughout from $X$ to $Y$
✓
absorbed from $X$ upto an intermediate point $Z$ (not shown in the figure) and then released from $Z$ to $Y$
D
released from $X$ upto an intermediate point $Z$ (not shown in the figure) and then absorbed from $Z$ to $Y$

✓

Answer

Correct option: C.

absorbed from $X$ upto an intermediate point $Z$ (not shown in the figure) and then released from $Z$ to $Y$

c
(c)

As we move along line $X Y$, it cuts a isotherm at higher temperature $\left(T_2 > T_3\right)$

$\left(T_2 > T_3\right)$ but then from $Z$ to $Y$ line moves to a low temperature isotherm. So, heat is absorbed upto $Z$ and then it is released from $Z$ to $Y$.

A small boy is throwing a ball towards a wall $6 \,m$ in front of him. He releases the ball at a height of $1.4 \,m$ from the ground. The ball bounces from the wall at a height of $3 \,m$, rebounds from the ground and reaches the boy's hand exactly at the point of release. Assuming the two bounces (one from the wall and the other from the ground) to be perfectly elastic, .......... $m$ far ahead of the boy did the ball bounce from the ground
