Question

Take a test tube and fill more than half of it with water. Now take an ice cube and wrap it with a wire gauze and

put it at the bottom of the test tube. Boil the water from above. It will be observed that the water at the top of

the test tube starts boiling but the ice does not melt. Why ?​

Answer 1

Answer:

When ice is wrapped in wire gauze and placed in water it does not melts even when the water boils because the container is made up of insulating material.

• Insulators are those substances which resists the flow of heat.

• When water starts boiling then heat is transferred from water to container, but the container is made up of insulator so heat did not able to cross the initial contact surface.

• Due to no heat transfer heat will not able to hit into the ice and it remains intact.
