What is it?

A jug is a container, usually with a handle and a spout, used for holding and pouring liquids like water, milk, or juice. It helps us measure and carry a certain amount of liquid easily from one place to another.

Simple Example

Quick Example

Imagine your family is having lunch, and your mother needs to pour water for everyone. She uses a jug filled with water to serve everyone at the table. This way, she can easily pour the right amount for each glass.

Worked Example

Step-by-Step

Let's say a jug can hold 1 litre of water. You need to fill 3 glasses, and each glass holds 250 ml.

STEP 1: Understand the jug's capacity: 1 litre = 1000 ml.
---STEP 2: Understand the glass capacity: 250 ml.
---STEP 3: Calculate how many glasses one full jug can fill: 1000 ml / 250 ml per glass.
---STEP 4: Perform the division: 1000 ÷ 250 = 4.
---ANSWER: One full jug can fill 4 glasses.

Why It Matters

Understanding jugs and capacity is fundamental in daily life, from cooking to science. Chefs use them to measure ingredients, and scientists use them for experiments. It's a basic skill for anyone working with liquids, ensuring accuracy and efficiency.

Common Mistakes

MISTAKE: Thinking all jugs hold the same amount of liquid. | CORRECTION: Jugs come in different sizes and capacities (e.g., 500 ml, 1 litre, 2 litres). Always check the marked capacity or estimate its size.

MISTAKE: Confusing the amount of liquid a jug can hold with its weight. | CORRECTION: Capacity refers to the volume of liquid (how much space it takes up), not how heavy the jug itself is.

MISTAKE: Overfilling a jug beyond its brim. | CORRECTION: Always fill a jug up to its marked capacity or just below the brim to prevent spills and ensure accurate measurement.

Practice Questions

Try It Yourself

QUESTION: A small jug can hold 500 ml of milk. If you need 1 litre of milk, how many times do you need to fill the small jug? | ANSWER: 2 times (1 litre = 1000 ml; 1000 ml / 500 ml = 2)

QUESTION: A jug has a capacity of 2 litres. If you pour 750 ml of water into it, how much more water can the jug hold? | ANSWER: 1250 ml or 1.25 litres (2 litres = 2000 ml; 2000 ml - 750 ml = 1250 ml)

QUESTION: A shopkeeper sells fresh juice. He has a large jug that holds 3 litres of juice. If each customer buys a glass with 200 ml of juice, how many customers can he serve from one full jug? | ANSWER: 15 customers (3 litres = 3000 ml; 3000 ml / 200 ml per customer = 15 customers)
