Question

which of the following is available in three states
(a) petrol
(b) water
(c) milk
(d) kerosine

Answer 1

Most likely water .. As it is found naturally in all those 3 states and even more...

Answer 2

Answer: (b) water

Explanation:

• The three states of matter are:-

Solid- the molecules in solid state are very closely packed with maximum intermolecular force and least intermolecular space. It is hard and rigid.

Liquid- the molecules are less closely packed than in solid. The intermolecular force of attraction is also less and the molecules also loosely packed. The liquid takes the shape of the container.

Gas- the molecules are packed very loosely with least intermolecular force and maximum intermolecular space. The molecules are free to go anywhere.

• Water is the substance which is available in all the three states very commonly.
• Hence, the required answer is "water".
