Question

The diagram below shows Hope's experimental set up. The temperature in the
metallic cylinder is 10° C. The trough is packed with a freezing mixture of ice
and salt.
(i) Which of the two thermometer shows rapid fall in temperature initially -
T1 or T2 and why?
(i) After some time when ice is formed:
1. Will it sink to the bottom of the metallic cylinder?
2. What does it tell about density of ice in relation to density of water at
the bottom?​

Answer 1

Answer:

The thermometer T1 shows rapid fall in temperature initially.

No,  the ice will float on the surface, because the ice has less density than that of water.
