The level of water in the beginning and at the
end of the activity remains the same. This is
because the sugar molecules do not take up

extra space but fit into the space between
the water molecules.

Liquids Dissolve in Liquids

When milk is added to water, at first the
colour of the milk spreads slowly in the
water. After stirring, the colour spreads

uniformly. This is because milk is completely
soluble in water. Here, both water and milk

are liquids. Hence, their solution is called a

Gases Dissolve in Liquids released

When we open a Soda can , you will
observe bubbles of gas coming out

of the soda. These are bubbles of a

gas called carbon dioxide . This
shows that soda is a liquid with a CO bubbles
