I WILL MARK BRAINLIST PLEASE HELP! Describe how the motion of the particles within the popcorn changes as thermal energy is transferred. How do they start out? How does that change? What other transformations occur?

Generally, when thermal energy is transferred to a material, the motion of its particles speeds up and its temperature increases. There are three methods of thermal energy transfer: conduction, convection, and radiation. ... Convection transfers thermal energy through the movement of fluids or gases in circulation cells.

Explanation:

Why do you think transferring energy into or out of a substance can change the molecules’ freedom of movement?

Explanation:

We know that transferring energy can cause a change in molecules' freedom of movement. Another way to say this is that transferring energy into or out of a substance can cause a phase change.
