Answer:

B

Explanation:

• On a microscopic scale, conduction occurs as rapidly moving or vibrating atoms and molecules interact with neighboring particles, transferring some of their kinetic energy. Heat is transferred by conduction when adjacent atoms vibrate against one another, or as electrons move from one atom to another.

Conduction occurs when two object at different temperatures are in contact with each other.Heat flows from the warmer to the cooler object until they are both at the same temperature

Answer:

a
