Question

which of these claims best represents the models below? p model 1 model 2 faster slower a. the particles in model 1 and model 2 have the same amount of thermal energy. b. thermal energy was removed from the particles in model 1 to produce the particle movement seen in model 2. c. the particles in model 2 are moving faster because they have less thermal energy than the particles in model 1. d. thermal energy was added to the particles in model 1 to produce the particle movement seen in model 2.

Explanation:

Step1: Recall thermal - energy concept

Thermal energy is related to particle motion. Faster - moving particles have more thermal energy.

Step2: Analyze the models

Model 1 has slower - moving particles (blue) and Model 2 has faster - moving particles (orange).

Step3: Evaluate each option

A: Particles in Model 1 and 2 don't have the same thermal energy as their motion speeds differ.
B: Removing thermal energy would slow particles down, not speed them up.
C: Faster - moving particles have more thermal energy, not less.
D: Adding thermal energy increases particle speed, which is consistent with the change from Model 1 to Model 2.

Answer:

D. Thermal energy was added to the particles in model 1 to produce the particle movement seen in model 2.
