Question

Choose the correct option:

1: Physical properties of ice, water, and steam are very different.

2: Chemical composition of water is different in all three states.

• A. only 1 is true
• B. only 2 is true
• C. both are true
• D. both are false

Answer 1

Answer: (A)

only 1 is true

The physical properties of ice, water, and steam are very different due to the different strengths of intermolecular forces.

The chemical composition of water is same in all three states. It is $H_{2}O$. Hence, the given statement is false.
