The Amazing World of Solutes Solvents and Solutions Class 8 Short Question Answer

Question 1.

What is the definition of a solute in a solution?

Answer:

A solute is the substance that is dissolved in a solvent to form a solution.

Question 2.

How does temperature generally affect the density of a substance?

Answer:

Generally, the density of a substance decreases with an increase in temperature due to the expansion of particles.

Question 3.

What is a saturated solution?

Answer:

A saturated solution is one in which no more solute can dissolve at a given temperature.

Question 4.

Why do oil and water not mix?

Answer:

Oil and water do not mix because they have different densities and polarities, with oil being less dense and non-polar, while water is polar.

Question 5.

What happens to the volume of a solid when it is heated?

Answer:

When a solid is heated, its volume generally increases due to the expansion of its particles, which can lead to a decrease in density.

Question 6.

What is a solute and how does it differ from a solvent?

Answer:

A solute is the substance that is dissolved in a solution, while a solvent is the liquid that dissolves the solute.

Question 7.

How does temperature affect the solubility of most solids in liquids?

Answer:

Generally, the solubility of most solids in liquids increases with an increase in temperature, allowing more solute to dissolve at higher temperatures.

Question 8.

What happens to the density of a substance when it is heated?

Answer:

When a substance is heated, its density typically decreases because the volume increases while the mass remains constant.
