Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which type of heat exchange involves the direct transfer of heat between molecules of objects in direct contact with each other?
A
Radiation
B
Evaporation
C
Conduction
D
Convection
Explanation: 

Detailed explanation-1: -Heat can be transferred in three ways: by conduction, by convection, and by radiation. Conduction is the transfer of energy from one molecule to another by direct contact.

Detailed explanation-2: -Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules.

Detailed explanation-3: -Conduction is heat transfer through stationary matter by physical contact. (The matter is stationary on a macroscopic scale-we know there is thermal motion of the atoms and molecules at any temperature above absolute zero.)

Detailed explanation-4: -Conduction of Heat Heat transfer takes place from one molecule to another molecule as a result of the vibratory motion of the molecules. Heat transfer through the process of conduction occurs in substances which are in direct contact with each other. It generally takes place in solids.

Detailed explanation-5: -Conduction happens when materials or objects are in direct contact with each other. The molecules in the warmer object vibrate faster than the ones in the cooler object. The faster vibrating molecules collide with the slower molecules. This makes the cooler molecules vibrate more quickly, and the object gets warmer.
