Question

To keep the volume of empty space in a vessel containing a liquid constant at all temperatures, the expansions of vessel and liquid should be the same. State whether the statement is true or false.

• A. True
• B. False
• C. Either
• D. Neither

Answer 1

Answer: (A)

True

As,

$V_{empty}=V_{vessel}-V_{water}$

$\Delta V_{empty}=\Delta V_{vessel}-\Delta V_{water}$

for no change in remaining volume at all temperatures.

$\Delta V_{empty}=0$

i.e, $\Delta V_{vessel}=\Delta V_{water}$

i.e, Expansion in vessel and water should be the same.

Hence option $\text{A}$ is correct.
