Question

show with an activity that liquids are less closely packed

Answer 1

A liquid has definite size (or volume) but indefinite shape. For example, milk is liquid. It takes the shape of its container but its volume remains the same irrespective of the size of the container. The particles of a liquid are not as closely packed as those of solid. The interaction between them is weak which allows liquids to flow freely. Water, coke, shakes, oil are examples of liquid.
