Question

When a liquid in a vessel is heated, its level continuosly rises. Then

• A. ${\gamma }_R$ is + ve & ${\gamma }_g$ =0
• B. ${\gamma }_R$ is + ve & ${\gamma }_g$ is-ve
• C. ${\gamma }_R={\gamma }_A$
• D. ${\gamma }_R={\gamma }_g$

Answer 1

Answer: (A), (B)

The correct options are
A ${\gamma }_R$ is + ve & ${\gamma }_g$ =0
B ${\gamma }_R$ is + ve & ${\gamma }_g$ is-ve

In case option 1 is correct, the liquid will expand and volume of vessel will remain constant. Hence, level of liquid will rise. This option is correct.

In case option 1 is correct, the liquid will expand and volume of vessel will decrease since its coefficient of volume expansion is negative. Hence, level of liquid will rise. This option is also correct.

In option C, liquid and vessel will expand at the same rate. Hence, level will remain constant.

Answer is option A and B.
