Chapter-  Filling and Lifting

SUMMARY NOTE:-

1. Capacity (How much a container can hold)

• Capacity means the amount of liquid a container can hold.
• Examples: A cup has a small capacity. A bucket has a large capacity.
• Capacity is measured in millilitres (ml) and litres (L).
• 1 litre = 1000 millilitres
• ½ litre is half of 1 litre and ¼ litre is one-fourth of 1 litre.
• ½ litre = 500 ml         ¼ litre = 250 ml
• Different vessels (glass, bowl, jug, bottle) can hold different amounts of liquid.
• Bigger containers hold more, smaller containers hold less.

2. Comparing Capacity

·      We compare capacity using words - more than / less than / equal to.
A bucket holds more water than a glass.

A bucket holds less water than a water tank.

A one-litre bottle holds water equal to one litre.

3. Volume

• Volume is the amount of space an object or a liquid occupies.
• Volume is the amount of space that a liquid takes up in a container.
• Examples: A glass can hold 200 ml of water — this is its volume.

A bucket has more volume than a mug.

• For liquids, we measure volume in millilitres (ml) and litres (L).

4. Weight – Heavy and Light

• Objects can be compared using balance.

·        Heavier object moves down when held or placed on a balance.

E. Short Answer Questions

1.   What is the use of measuring cups?

Ans - Measuring cups are used to measure the volume of liquids.

2.   Why do we compare heavy and light things?

Ans - We compare heavy and light things to understand their weights so that we can use them correctly and safely in our daily activities.

3.   How can you check which ball is heavier using a balance?

Ans - To check which ball is heavier using a balance, place one ball on each side of the balance. The side that goes down has the heavier ball, and the side that goes up has the lighter ball.
