Question

When a pot of water sits on a hot stove, the metal pot is heated, and then transfers its heat to the water. A student claims that conduction is the only type of heat transfer occurring. Which statement explains why the student's idea is incorrect?

Conduction cannot occur between two different phases of matter.
The water transfers heat within the pot by convection.
Water cannot be heated by electromagnetic radiation.
Metal is a poor conductor of heat.

Answer 1

it is B

The water transfers heat within the pot by convection.

Answer 2

The correct answer is the first statement.

Step-by-step explanation:

During heating of a fluid, the cooler substance, that is, denser in nature will sink to the bottom, while the hot substance, which is less dense in nature will elevate at the top. This material flow instigates current and the phenomenon is called convection. For example, during the heating of a metal pot of water, the transferring of heat takes place from the pot to the water signifying the process of convection.

On the other hand, when two objects are coming in contact with each other and both of them exhibit distinct temperature then the flow of heat takes place towards the cooler object from the warmer object. This phenomenon is called conduction. Therefore, it can be stated that the process of conduction cannot take place between two distinct phases of matter.
