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.

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.

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

the answer is kevlar
