What must happen for molecules to move slower?
Kinetic energy is not changing. Temperature decreases.
Kinetic energy and temperature depend on the molecules.
Kinetic energy is decreasing and temperature is decreasing.
Kinetic energy is decreasing and temperature is increasing.
Molecules are always moving no matter what phase they are in: solid, liquid, gas.
True
False
What would be a reason for a phase change to occur in one substance and not another substance even if both substances began at the same phase and were transferred the same amount of energy?
The molecular attraction of one of the substances was weaker than the other substance causing phase change to occur.
The molecular attraction of both substances were the same causing phase change to occur in one of them.
The molecular attraction of one of the substances was stronger than the other substance causing phase change to occur.
Phase change can not occur in one substance and not the other because they both started in the same phase.
In order to increase the speed of a substance's molecules, someone must...
transfer energy into the substance.
transfer energy out of the substance.
lower the temperature of the substance.
keep the temperature the same for the substance.
Which options are correct about molecular attraction and freedom of movement?
High molecular attraction = High freedom of movement
Low molecular attraction = Low freedom of movement
Low molecular attraction = High freedom of movement
These two vocabulary words have nothing to do with each other.
