When a fork is placed in a hot piece of lasagna, thermal energy is transferred up the fork by

A. fast-moving particles travelling along the fork.

B. fast-moving particles changing places with slow-moving particles.

C. fast-moving particles colliding with slow-moving particles.

D. fast-moving particles colliding with other fast-moving particles.

Respuesta :

C. fast-moving particles colliding with slow-moving particles.

Answer: Option (C) is the correct answer.

Explanation:

It is given that there is a hot piece of lasagna, therefore, the particles of lasagna will have high kinetic energy. As a result, they will be moving rapidly from one place to another.

And when a fork is placed on a hot piece of lasagna then heat will be transferred from fast moving particles of lasagna collide with slow moving particles of the fork.
