Question

Choose whether each statement below is true or false.
The motion of a the particles in a substance and the temperature of that substance are directly related.
The particles in a substance are closest together when there is less energy.
As the energy and temperature of a substance increase, the movement of the particles decreases.
The state of matter of a substance can be changed by decreasing or increasing the temperature.

Answer 1

Here are the evaluations of the statements:

1. **The motion of the particles in a substance and the temperature of that substance are directly related.**
**True** - As the temperature of a substance increases, the kinetic energy of its particles also increases, leading to greater motion.

2. **The particles in a substance are closest together when there is less energy.**
**True** - Generally, in solids, the particles are densely packed together, and as energy (and temperature) increases, particles tend to move further apart, moving into liquid or gas states.

3. **As the energy and temperature of a substance increase, the movement of the particles decreases.**
**False** - As energy and temperature increase, the movement of the particles actually increases.

4. **The state of matter of a substance can be changed by decreasing or increasing the temperature.**
**True** - Changing the temperature of a substance can lead to phase changes, such as solid to liquid (melting) or liquid to gas (evaporation), and vice versa.

Overall Evaluations:
1. True
2. True
3. False
4. True
