when a fork is placed in a hot piece of lasagna, thermal energy is transferred up the fork by\no fast - moving particles travelling along the fork.\no fast - moving particles changing places with slow - moving particles.\no fast - moving particles colliding with slow - moving particles.\no fast - moving particles colliding with other fast - moving particles.

Answer

Brief Explanations:

Thermal conduction in a solid (the fork) occurs when fast - moving particles (in the hot end) collide with slow - moving particles (in the cooler end), transferring energy. This is the mechanism of heat transfer by conduction.

Answer:

fast - moving particles colliding with slow - moving particles.
