Question

Water can be poured into a bottle easily whereas a rock cannot as shown in the image below. Identify the reason behind this.

• A. Rock is liquid, water is solid
• B. Rock is gas, water is liquid
• C. Rock is solid, water is liquid
• D. Rock is plasma, water is liquid

Answer 1

The correct option is C Rock is solid, water is liquid

Solids have a definite shape and size. Due to the rigidity in the solid, they cannot change the shape. Hence, it cannot enter the bottle easily.

Water on the other hand is a liquid. They do not have a fixed shape so it can easily get into the bottle and take the shape of the bottle.
