Definition

What is it?

When a container has reached its maximum capacity and cannot hold anything more, it is considered full. This means there is no empty space left inside for additional items or liquid.

Simple Example

Quick Example

Imagine your school water bottle. If you fill it completely with water right up to the brim, so no more water can go in, then your water bottle is full. You can't add even one more drop without it spilling out.

Worked Example

Step-by-Step

Let's say you have a glass that can hold 200 ml of juice.

1. You start pouring juice into the empty glass.
---2. You continue pouring until the juice level reaches the top edge of the glass.
---3. No more juice can be added without it overflowing.
---4. At this point, the glass contains 200 ml of juice, which is its maximum capacity.
---5. Therefore, the glass is full.

Answer: The glass is full when it holds 200 ml of juice, its maximum capacity.

Why It Matters

Understanding 'full' is fundamental in science, engineering, and daily life. Scientists use it when measuring chemicals, engineers when designing storage tanks, and even delivery services like Zomato when packing orders. It's crucial for managing resources and preventing waste.

Common Mistakes

MISTAKE: Thinking a container is full even if there's a little space left at the top. | CORRECTION: A container is only truly full when it cannot hold ANY more, right up to its maximum capacity.

MISTAKE: Confusing 'full' with 'heavy' or 'many'. | CORRECTION: 'Full' specifically refers to capacity, not weight or quantity in general. A small container can be full with a light item, and a large container can be full with fewer, larger items.

MISTAKE: Believing 'full' applies only to liquids. | CORRECTION: 'Full' applies to anything a container can hold – liquids, solids like rice or toys, or even gases.

Practice Questions

Try It Yourself

QUESTION: If a tiffin box is packed with roti and sabzi such that the lid can barely close and no more food can be added, is the tiffin box full? | ANSWER: Yes, the tiffin box is full.

QUESTION: A bucket can hold 10 litres of water. If you pour 8 litres into it, is the bucket full? Explain why or why not. | ANSWER: No, the bucket is not full because it can still hold 2 more litres of water (10 - 8 = 2).

QUESTION: Your phone's storage capacity is 128 GB. If you have used 127.5 GB, is your phone's storage considered full? What does this mean for installing new apps? | ANSWER: Yes, your phone's storage is almost full. It means you have very little space (0.5 GB) left, so installing new apps might be difficult or impossible without deleting something first.

MCQ

Quick Quiz

Which of these describes a 'full' container?

A glass with some water in it.

A basket with a few apples at the bottom.

A petrol tank completely filled to the brim at the fuel station.

A school bag with only one book inside.

The Correct Answer Is:

Option C describes a petrol tank filled to its maximum capacity, meaning no more petrol can be added. The other options describe containers that still have plenty of empty space.

Real World Connection

In the Real World

When you buy milk in a packet, the company ensures the packet is 'full' with the exact amount of milk mentioned (e.g., 500 ml). Similarly, when you recharge your mobile data, your data plan is 'full' at its maximum limit (e.g., 2 GB per day), and once you use it all, your data is 'full' and you can't use more without topping up.
