MCQ: Boyle's law states that

1. pressure of a gas is inversely proportional to its volume i.e. P × V = constant
2. pressure of a gas is directly proportional to its volume i.e. P⁄V = constant
3. pressure of a gas is inversely proportional to the square of its volume i.e. P × V² = constant
4. pressure of a gas is directly proportional to the square of its volume i.e. P ⁄ V² = constant
