Answer 1

Answer:

Milk = Liquid

Water = Liquid

Pepsi = Liquid

Humid = Gas

Air = Gas

Sea = Liquid

Pollutants in air = Gas

plz mark me as brainiest

Answer 2

Answer:

• The solute and solvent for the following solutions are:

Air - Nitrogen is the solvent and Oxygen is the solute.

Milk - Water (85%) is the solvent and components like lactose, proteins, vitamins, minerals, calcium phosphate etc are the solutes.

Pure water - It is a solvent.

Pepsi - Sugar, specifically, high fructose corn syrup is the solute and water is the solvent.

Humid - Water is the solute and air is the solvent.

Sea - Water is the solvent and sodium chloride (NaCl) is the solute.

Pollutants - Dust particles are the solute and air is the solvent.

• The state of these solutions:

Air - gas

Milk - liquid

Water - liquid

Pepsi - liquid

Humid - gas

Sea - liquid

Pollutants - gas

Explanation:

What is a solute?

• A solute is a substance that is dissolved in a solution.
• It can appear in various forms like solid, liquid or gas.
• The solvent in the solution breaks down the solute molecules and distribute them equally.
• The measurement of solute in a solution depends on its concentration.
• Examples: sodium chloride in sea water, oxygen in air, proteins, minerals, vitamins etc in milk; sugar in Pepsi, water in humid; and dust particles in pollutants.

What is a solvent?

• A solvent is a substance that dissolves solute which results in the formation of a solution.
• It also occurs in various states like solid, liquid or gas.

• Solvents can be classified into:

1. Polar and non-polar (based on its affinity towards water).
2. Water-miscible and water-immiscible (based on miscibility with water).
3. Natural and synthetic (based on the origin).

• Examples: Nitrogen in air; water in milk, Pepsi, humid etc; and air in pollutants.

States of Matter

• A state of matter is the form in which a matter exists.
• There are 4 states of matter: solid, liquid, gas and plasma.
• Solid is a state of matter in which molecules are closely packed together with least amount of kinetic energy.
• Examples: gold, wood, brick etc.
• Liquid is a state of matter which retains a constant volume but no fixed shape and takes the shape of its container.
• Examples: water, milk, honey etc.
• Gas is a state of matter in which molecules are loosely packed and freely moves from one place to another.
• Examples: hydrogen gas; compound like carbon dioxide etc.
