Question

Which best describes the way particles move to heat objects using conduction?
A
Objects generate electromagnetic waves are carried away from the object emitting them.

B
Fast-moving particles collide with slower moving particles transferring their heat energy.

C
Fast moving particles in warm objects collide with electromagnetic waves.

D
Particles expand with thermal energy, hot air rises and pushes cooler air down through circulation.

Answer 1

Answer:

B  Fast-moving particles collide with slower moving particles transferring their heat energy.

Explanation:

Thermal conduction is one of the three modes of heat transfer between bodies. It usually expressed by the exchange of heat contents by a fast moving body colliding with a slower one.

The fast moving body loses heat and the slow one gains the heat.

• Heat is a form of kinetic energy that possess attributes of motion.
• It is transferred in three major ways; conduction, convection and radiation.
• Conduction takes place between two more bodies in contact.
• On a molecular level, the collision of fast moving particles with slower ones transfers the heat energy.
