Question

Akriti takes two containers P and Q, both half-filled with water. She places a hot metal block in container P and an ice block in container Q. After sometime the temperature in both the containers is stabilized.
Which of the following correctly shows the mode(s) by which heat was transferred between water and the metal block in container P and water and the ice block in container Q?
 Only conduction
 Only convection
 Both conduction and convection
Justify your answer for both cases with detailed explanation.

Answer 1

Answer:

An insulated container is filled with a mixture of water and ice at. Another container is filled with water that is continuously boiling at. In a series of experiments, the containers are connected by various thick rods that pass through the walls of the containers (see the diagram). The rod is insulated in such a way that there is no heat loss to surroundings. In experiment 1, a copper rod is used, and the ice melts inmin. In experiment 2, a steel rod of the same cross section is used, and the ice melts inmin. How long ( in min) would it take to melt the ice if the two rods are used "in series
