Question

In a solid, the molecules

are rapidly moving

are randomly moving in a slow pattern

are tightly bound together, and vibrating in a fixed position

do not exist

The theory that says that all matter is made up of moving molecules is called:

The Molecular Theory

The Kinetic Theory of Matter

The Theory of Moving Molecules

The States of Matter Theory

What happens to the molecules when water is boiled? Describe their motion.

What happens to the molecules when water is frozen? Describe their motion.

Water has different molecules in each of the three states.

True

False

Answer 1

In a solid:

are tightly boung together and vibrating in fixed position

The theory that says all matter is made up of moving molecules is:

The kinetic molecular theory

When water is boiled, the heat of the water causes the molecules to collide rapidly. This in turn causes high energy collisions which free the hydrogen bonds, the polar bonds, and this allows molecules to escape. This only happens when each molecule's activation energy exceeds the bond energy.

When water is frozen, the molecules spread out and create a six sided crystalline structure which is why water is less dense than liquid. The molecules still vibrate in place, but are more stable.

This phase diagram proves water can exist in three states at the triple point:

Answer 2

1. are tightly bound together, and vibrating in a fixed position

2. The Kinetic Theory of Matter

3. Speed up, move frantically

4. Slow down

5. False

Answer 3

Answers:

Rapidly Moving

Molecular Theory

Molecules in water evporate into steam while boiled. Molecules move very fast. Liquid becomes a gas.

Molecules start to move very slowly when water is frozen. Liquid becomes a solid.

True

Answer 4

Are tightly bound together, and vibrating in a fixed position

The Kinetic Theory of Matter

They move around more easily, than they do in a solid. They also have more space to vibrate, but do not go crashing everywhere.

They are tightly packed together with hard;y any space to move.

False.

I laid out the answer more readable than the others.!

Answer 5

In a solid, the molecules are tightly bound together, and vibrating in a fixed position.

The theory that says that all matter is made up of moving molecules is called The Kinetic Theory of Matter.

Water vapor is the result of boiling water. Molecules will are rapidly moving and are not fixed to each other.

Water molecules in frozen water are vibrating but are fixed to each other.

Water has different molecules in each of the three states: False.
