Question

Water is a bad conductor of heat because

• A. It has excess free electrons.
• B. It has high pH.
• C. It lacks free electrons.
• D. It has low pH.

Answer 1

The correct option is C

It lacks free electrons.

The explanation for the correct option:

1. The electrons in water are involved in chemical bonds, they are not free to participate in conduction.
2. Hence, water lacks free electrons.
3. Materials that conduct heat well are referred to as good conductors, while materials that do not conduct heat well are referred to as bad conductors or insulators.
4. As a result, water acts as an insulator.

Hence, Option(C) is correct.
