What are solutes and solvents?

A solute is the minor component of a solution. It is what is dissolved in the solvent. All solutes have solubility, which is having the
ability to be dissolved. The types of

This is a diagram of a solute and solvent.
solutes consist of chemicals, gases, solids, and liquids. A solvent is what dissolves something.
A solvent can be a chemical, gas, solid, or liquid.

What is freezing point?

The freezing point of a specific type of matter is the temperature at which the state of the matter coexist indefinitely.
This means that the matter is in the process of going from a liquid to a solid. That is why it is also called the melting point.
The melting point or freezing point of water is zero degrees Celsius, that is only if the solvent is not disturbed by a solute.

How do solutes affect the freezing point of a solvent?

Since you know what solutes and solvents are, you can now find out how solutes affect the freezing point
of solvents. It can lower the freezing point by adding pressure to the solvent. When the solute expands, it
adds to the pressure in the solvent. By adding pressure to the water, it lowers the freezing point. A solute
can also lower the freezing point by adding more molecules to the number molecules that are already present
in that solvent. This means that the number of molecules in the solute plus the molecules in the solvent makes
the solution more dense which makes it take longer to freeze. For example, if you add salt to water, it will lower
the freezing point. This is because the molecules in the salt were added to the molecules in the water.

How do solutes affect the boiling point of a solvent?

When you add a solute to a solvent the boiling point will be at a higher temperature than the solvent by itself. Since
the solution is at a higher temperature, it will start to boil slower.

What is boiling point?

Boiling point is when a specific matter starts to turn into a gas. It is also called the vapor point.

What solutes affect the boiling point of water

Salt affects the boiling point of water. a small amount of salt doesn’t matter much but a medium or large amount
of salt will change the boiling point of water. Another solute that affects the boiling point is sugar. Sugar is kind of
like salt small quantities don’t matter but larger quantities make water boil slower. Another example of solutes that
raise the temperature of a solvent would be ethylene glycol, which is also called antifreeze, in a cars cooling system.

This is water that has reached it's boiling point.

The antifreeze makes the car able to have a higher operating temperature by making the boiling point higher.

What is a solute and solvent

A solute is the substance to be dissolved, such as sugar. The other is a solvent. The solvent is the one doing the
dissolving such as water. Most of the time there is more solvent than solute.
