Question

a pan of water is set on a stove. after the heat is turned on the temperature of the water begins to and thermal energy of the water

Answer 1

Answer:

Here, there is one point of heating, that is the bottom of the pan. When the bottom water is heated, it moves up and cold water takes its place at bottom. And the process continues till all water is heated. This process of heating is called convection

Answer 2

When the stove is turned on, the temperature of the water begins to increase, and the thermal energy of the water increase.

• When heat is applied, the water molecules closer to the heat begin to get heated up and thus start vibrating.
• This vibration will cause all the surrounding molecules to vibrate and this continues.
• As a result, the heat gets transferred and the overall temperature increases.
• Thermal energy is the net energy of all the molecules present in the system.
• The rise in temperature of each molecule will result in a rise in the system's total energy which is the internal energy.
