Capacity
Capacity is the amount of liquid a container can hold. We use units like litres and millilitres to measure it.
Standard Units of Capacity
Litre is the standard unit used to measure liquids like milk, water, and oil. Smaller quantities are measured in millilitres.
Heavy and Light (Weight)
Objects that are difficult to lift are called heavy, while objects that are easy to lift are called light.
Estimation and Comparison
Comparing different containers to see which one holds more or less water by filling them up and pouring.
Non-Standard Units
Using everyday objects like spoons, cups, and mugs to measure how much liquid a bigger vessel can hold.
