Definition

What is it?

In terms of capacity, 'empty' means that a container or space has nothing inside it. It holds no items, liquid, or air. An empty container is ready to be filled.

Simple Example

Quick Example

Imagine your school water bottle after you've drunk all the water during break time. There's no water left inside. That means your water bottle is empty.

Worked Example

Step-by-Step

Let's say you have a glass jar that can hold 500 grams of ladoos.

1. You open the jar and see that there are no ladoos inside.
---
2. Since there are zero ladoos, the jar is not holding any amount of its capacity.
---
3. If you were to weigh the contents, you would find 0 grams of ladoos.
---
4. This means the jar is completely empty and ready to be filled with new ladoos.

Answer: The jar is empty.

Why It Matters

Understanding 'empty' is fundamental in daily life, from cooking to managing inventory. Engineers use this concept when designing storage tanks, and logistics managers ensure trucks are not empty on return trips to save fuel. It's crucial for efficiency and planning.

Common Mistakes

MISTAKE: Thinking 'empty' means 'broken' or 'useless'. | CORRECTION: An empty container is often perfectly fine; it just doesn't have anything inside it at the moment. It's ready for use.

MISTAKE: Confusing 'empty' with 'partially full'. | CORRECTION: 'Empty' means absolutely nothing inside, zero content. 'Partially full' means there is some content, but not to its maximum capacity.

MISTAKE: Assuming an empty container has no weight. | CORRECTION: An empty container still has its own weight (like an empty tiffin box). 'Empty' refers only to the absence of contents, not the container itself.
