Let's evaluate each statement one by one:
-
"The motion of the particles in a substance and the temperature of that substance are directly related."
- True: Generally, as the temperature of a substance increases, the motion of its particles also increases.
-
"As the energy and temperature of a substance increase, the movement of the particles decreases."
- False: As the energy and temperature of a substance increase, the movement of the particles actually increases.
-
"The state of matter of a substance can be changed by decreasing or increasing the temperature."
- True: Changes in temperature can transition a substance between solid, liquid, and gas phases.
-
"The particles in a substance are closest together when there is less energy."
- True: At lower energy (and lower temperature), particles in a substance tend to be closer together, as seen in solids.
So the answers are:
- True
- False
- True
- True
