**MCQ 1**: Van der Waals derived an expression for the ‘pressure defect’, if the observed pressure is denoted as ‘p’ and volume is denoted as ‘V’, the gas pressure in the bulk of the gas is equal to:

- p + a/V; where a: constant for the particular gas
- p + a/(V²); where a: constant for the particular gas
- p + (a × V); where a: constant for the particular gas
- p + (a × V²); where a: constant for the particular gas

**MCQ 2**: Boyle's law states that

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