MCQ. Van der Waals derived an expression for ‘pressure defect’, if observed pressure is denoted as ‘p’ and volume is denoted as ‘V’, gas pressure in bulk of gas is equal to:

1. p + a⁄V; where a: constant for particular gas
2. p + a⁄(V²); where a: constant for particular gas
3. p + (a × V); where a: constant for particular gas
4. p + (a × V²); where a: constant for particular gas

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 square of its volume i.e. P × V² = constant
4. pressure of a gas is directly proportional to square of its volume i.e. P ⁄ V² = constant
