Mr. G showed the class a container of salt. He poured the salt into a cup. What state of matter is the salt in and why?
Salt is a liquid because it takes the shape of the container.
Salt is a liquid because it pours just like water does.
Salt is a solid because it takes the shape of its container.
Salt is a solid because each salt crystal has a definite shape.

independent of
the same as
greater than
less than

According to the Kinetic Molecular Theory a liquid's (SELECT ALL THAT APPLY)
Particles are held close together by intermolecular forces.
Particles are in constant motion.
Particles are vibrating in place and closely packed.
Particles are not moving.
A liquid has the following characteristics except _____________.
Very little space between particles.
Particles that have have no definite pattern.
Particles hold that a very definite pattern.
Particles that freely flow past each other.
As the temperature of a substance increases:
The speed, and average kinetic energy of the particles, both increase.
The speed, and average kinetic energy of the particles, both decrease.
The speed of the particles increases, but the average kinetic energy of the particles decreases.
The speed of the particles decreases, but the average kinetic energy of the particles increases.
Adding heat to a solid makes the particles move...
Particles in a solid are not moving.
Slower
At the same rate as before the heat was applied.
Faster
Which is not true about the Kinetic Molecular Theory?
Gas molecules have forces of attraction for each other.
Collisions between gas molecules lead to a transfer of energy that is conserved.
Gas molecules have a negligible volume compared to the volume they occupy.
Gas molecules move in a random, straight-line motion.
