Question

If equal weights of all the three states of a substance X are taken, which state will have the MAXIMUM number of molecules?
A - solid
B - liquid
C - gas
D - (All three will have the same number of molecules.)

Answer 1

The answer is D) because only the physical state of the matter is being changed but not the chemical. Hence all three will have the same number of molecules.

Answer 2

The correct answer is option:

(D) All three will have the same number of molecules.

- In the given condition, the taken weights of all the three states of a substance are equal.

- Also there is not any other substance involved.

- Since the substance is same, no matter what its physical state is, it contains the same no of molecules.

- Hence, all three will have the same number of molecules.
