Test: Solids, Liquids & Gases - 1 - Question 4

What allows gases to expand and fill any available space?

Detailed Solution for Test: Solids, Liquids & Gases - 1 - Question 4
  • Gases can expand and fill any space because they are packed very loosely, giving them lots of space to move freely.
  • This means that gases can spread out to fit wherever they are put without any difficulty.
  • So, when you see a balloon getting bigger and bigger, it's because the gas inside it is spreading out to take up all the space it can find.
Test: Solids, Liquids & Gases - 1 - Question 5

State whether the following statement is True or False:

Molecules in solids are closely packed together, which allows them to move freely.

Detailed Solution for Test: Solids, Liquids & Gases - 1 - Question 5

In simple words: In solids, molecules are tightly packed together, not allowing them to move freely. This closeness gives solids their definite shape and volume.

Test: Solids, Liquids & Gases - 1 - Question 6

Why do ice cubes float in a tumbler of soft drinks?

Detailed Solution for Test: Solids, Liquids & Gases - 1 - Question 6
  • Ice cubes float in a tumbler of soft drinks because they are lighter than water.
  • This happens because ice is a special kind of solid that is less dense than liquid water.
  • When water freezes into ice, it expands and becomes less heavy, making it float on top of the liquid water.
  • So, when you see ice cubes floating in your drink, it's because ice is lighter than the liquid it's in.
Test: Solids, Liquids & Gases - 1 - Question 7

Which process involves changing a solid into a liquid on heating?

Detailed Solution for Test: Solids, Liquids & Gases - 1 - Question 7

Melting is the process of changing a solid into a liquid on heating.

Test: Solids, Liquids & Gases - 1 - Question 8

State whether the following statement is True or False

When you open a bottle of a fizzy drink like cola, the bubbles that come out are water vapor bubbles.

Detailed Solution for Test: Solids, Liquids & Gases - 1 - Question 8
  • When you open a bottle of a fizzy drink like cola, the bubbles that come out are not water vapor bubbles. They are bubbles of carbon dioxide gas. So, the correct answer is False.
  • Fun Fact: Fizzy drinks are a solution of the gas carbon dioxide in water, which gives them their bubbly nature!
Test: Solids, Liquids & Gases - 1 - Question 9

Which of the following is not a physical change?

Detailed Solution for Test: Solids, Liquids & Gases - 1 - Question 9

Rusting of iron is a chemical change because it involves a reaction between iron and oxygen, resulting in the formation of a new substance (iron oxide).

Test: Solids, Liquids & Gases - 1 - Question 10

What are atoms?

Detailed Solution for Test: Solids, Liquids & Gases - 1 - Question 10
  • Atoms are like the tiniest building blocks of everything around us.
  • Just like how Lego blocks help us build fun things, atoms are like the Lego blocks of matter, which is everything that has mass and takes up space.
  • So, atoms are the smallest units of matter that make up everything we see and touch.
