Which of the following is an example of conduction?
A
A radiator warming a room
B
Feeling warmth of the suns rays
C

D
Proximity to an object of exactly the same temperature.
Explanation: 

Detailed explanation-1: -Some examples are: Conduction: Touching a stove and being burned. Ice cooling down your hand.

Detailed explanation-2: -Hence, ice melting is an example of convection.

Detailed explanation-3: -For ice to melt, it must gain energy from the surroundings. Energy can be transferred (move) from the surroundings to the ice by conduction through the metal or plastic. Metal is a better conductor than plastic, so energy is transferred more quickly through the metal.

Detailed explanation-4: -The energy addition is converted to a different form; thus, the temperature does not change. Conduction is heat transfer via direct contact between two objects, which describes the transfer between the hot surface and the ice.

Detailed explanation-5: -A lizard warming its belly on a hot rock. Touching a hot seatbelt when you get into a car. A blacksmith heating up a sword in hot coals, and the heat transferring up through the metal. The heat from a stovetop transferring into a metal pot of water. 12-Aug-2021
