Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Conduction is the transfer of heat energy by ____
A
direct particle contact
B
electromagnetic waves
C
density differences
D
movement through a vacuum
Explanation: 

Detailed explanation-1: -Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. Conduction occurs more readily in solids and liquids, where the particles are closer together than in gases, where particles are further apart.

Detailed explanation-2: -Conduction is the transfer of energy from one molecule to another by direct contact. This transfer occurs when molecules hit against each other, similar to a game of pool where one moving ball strikes another, causing the second to move.

Detailed explanation-3: -Conduction is the transfer of heat between substances that are in direct contact with each other. The better the conductor, the more rapidly heat will be transferred. Metal is a good conduction of heat. Conduction occurs when a substance is heated, particles will gain more energy, and vibrate more.

Detailed explanation-4: -The three types of thermal energy transfer are conduction, convection and radiation. Conduction involves direct contact of atoms, convection involves the movement of warm particles and radiation involves the movement of electromagnetic waves.

Detailed explanation-5: -Every process involving heat transfer takes place by only three methods: Heat is transferred by three different methods: conduction, convection, and radiation. Heat conduction is the transfer of heat between two objects in direct contact with each other.
