Question

1. choose the best answer. which particle model best represents this scenario?

Explanation:

The scenario shows heating a liquid in a flask, which increases the thermal energy of the particles. When heated, liquid particles move faster and have greater kinetic energy, resulting in more active, wider-ranging motion (represented by the longer path lines in the right model). The left model shows slower, less energetic particle movement, typical of an unheated or cooler liquid.

Answer:

The right particle model (with particles showing longer, more dynamic movement paths) best represents this scenario.
