• A. a-g, b-e, c-f, d-h
• B. a-h, b-f, c-e, d-g.
• C. a-e, b-f, c-g,d-h
• D. a-f, b-g,c-h,d-e

Answer 1

Answer: (B)

a-h, b-f, c-e, d-g.

${\gamma }_g<{\gamma }_r⟹$ liquid expands more than the glass containing it. But the glass gets heated first. So the liquid level first decreases and then increases.

${\gamma }_g$ is negative implies that the volume of the container decreases continuously. Hence the level of the liquid increases continuously.

${\gamma }_g={\gamma }_r$ implies that both liquid and container expand equally. Hence no change in the level of liquid is observed.

${\gamma }_g>{\gamma }_r$ implies that container expands more than the liquid with change in temperature. Hence the liquid level decreases continuously.
