Particles in each state of matter behave differently because they have different amounts of thermal energy. For each statement below, select whether it is true or false.

Question

True False
Particles in a solid are packed tightly.

Particles in a solid have thermal energy.

Particles in a solid are completely still.

Answer 1

Here are the evaluations for each statement:

1. Particles in a solid are packed tightly.
   True - In a solid, particles are closely packed together in a fixed arrangement.

2. Particles in a solid have thermal energy.
   True - Particles in a solid possess thermal energy, which allows them to vibrate in place, even though they do not move freely.

3. Particles in a solid are completely still.
   False - Particles in a solid are not completely still; they vibrate around fixed positions, but they do not move freely like in liquids or gases.
