  • This property allows them to expand and fill the shape of the container they are in.
  • Additionally, gases are compressible due to the large spaces between particles, have low density compared to solids and liquids, and do not have tightly packed particles.

Air has _____ and takes up _____.

Detailed Solution: Question 5

Air has weight and takes up space. This means that even though we can't see air, it still has some weight and fills the space around us. Imagine blowing up a balloon, the air you blow into it gives the balloon weight and fills it up just like how air fills the space around us.

Test: Solids, Liquids & Gases- 2 - Question 6
Save

Which process would be used to separate sugar from a sugar-water solution?

Detailed Solution: Question 6

Evaporation is used to separate sugar from a sugar-water solution. By heating the solution, the water evaporates, leaving behind the sugar crystals. This method works because sugar dissolves in water but does not evaporate with it.

Test: Solids, Liquids & Gases- 2 - Question 7
Save

What happens to the rate of diffusion when a substance changes from a solid to a liquid?

Detailed Solution: Question 7

The rate of diffusion increases when a substance changes from a solid to a liquid. In liquids, particles are less tightly packed and can move more freely compared to solids, allowing for faster diffusion.

Test: Solids, Liquids & Gases- 2 - Question 8
Save

What is the outcome when a substance undergoes condensation?

Detailed Solution: Question 8

Condensation involves a substance changing from a gas to a liquid. For example, water vapor in the air condenses into liquid water when cooled, such as when steam forms droplets on a cold surface.

Test: Solids, Liquids & Gases- 2 - Question 9
Save

Which of the following is an example of an insoluble substance in water?

Detailed Solution: Question 9

Tea leaves are an example of an insoluble substance in water. Unlike sugar and salt, which dissolve, tea leaves do not dissolve in water. They remain separate and can be filtered out from the liquid.

Test: Solids, Liquids & Gases- 2 - Question 10
Save

What is the role of a solute in a solution?

Detailed Solution: Question 10

A solute is a substance that dissolves in a solvent to form a solution. For example, when sugar is added to water, it dissolves (solutes) to form a sweet solution. The solute integrates into the solvent to create a uniform mixture.
