What is the matter?
Everything matters.
What is freezing?
When a liquid changes state to become a solid.
Do the intermolecular forces weaken or strengthen when frozen?
They strengthen when frozen because they are so close and patched together.
If you heat up water until 100℃ what will happen?
It will begin to boil.
What is sublimation?
Sublimation is the process of solid into a gas.
What are the three types of state of matter?
Solid liquid gas
What is the freezing point?
The temperature at which a substance turns from a liquid to a solid.
What is the strongest intermolecular force out of solid, liquid, and gas?
They are strongest in solids because the particles are so close together.
Different liquids have different_
Boiling points.
What is condensation?
A phase change in
which a gas substance changes into a
liquid state.
What is the boiling point of water?
100 degrees celsius
What are other freezing phenomena?
Rain, sleet, and snow
Can intermolecular forces change in different liquids?
No they do not because it is still liquid and some might be thicker than others but they are the same.
We can clean dirty water by_
Boil the water.
What is deposition?
A phase change in which a
gas substance changes into a solid
state without first passing through the
liquid state.
What is mass?
Measure the amount of matter in an object.
What is freezing rain?
Rain that has changed state to a solid when it hits the ground
What is an intermolecular force?
They are what holds particles together in a solid liquid and gas.
What is the boiling point of liquid helium?
The boiling point of liquid helium is -269℃
What is evaporation
Liquid to gas
What is Principle of conservation of mass?
The total mass of substance doesn’t change during a chemical reaction.
How does freezing rain form?
1. Way up in the sky when the temperature is colder.
2. In winter, all precipitation initially falls as snow.
3. When we get freezing rain, it occurs when rain falls and then turns to ice as it hits the ground.
Are there different types of types of intermolecular forces?
No. they have different level of strength but they are all the same
What is the boiling point of Mercury?
The boiling point of Mercury is 356.9℃.
What depostion
Gas to solid
