Simple Kinetic Theory of Matter MCQs with Answers PDF Download – Test 1

MCQ 1: Air trapped inside a single-piston-cylinder exerts a pressure of 760 mmHg. If its volume is increased by 30% at a constant temperature, the pressure exerted would be equal to:

1. 533 mmHg
2. 544 mmHg
3. 584 mmHg
4. 633 mmHg

MCQ 2: According to kinetic molecular model, in gases,:

1. The particles are closely packed together, they occupy minimum space and are usually arranged in a regular pattern
2. The particles occur in clusters with molecules slightly further apart
3. The molecules are very far apart and occupy all the space made available to them
4. The particles vibrate about fixed positions and are held together by the strong intermolecular bonds between them

MCQ 3: Air trapped inside a single-piston-cylinder exerts a pressure of 760 mmHg. If its volume is increased by 20% at a constant temperature, the pressure exerted would be equal to:

MCQ 4: For a constant temperature, Boyle's law states that:

1. the pressure of a fixed amount of gas is directly proportional to the volume of the gas
2. the pressure of a fixed amount of gas is inversely proportional to the volume of the gas
3. the pressure of a fixed amount of gas is independent of the volume of the gas
4. None of the above

MCQ 5: If air at a pressure of 2 MPa is compressed such that the new volume of the air is one eighth of its initial volume, then the new pressure of the air is:

1. 0.25 M Pa
2. 2 M Pa
3. 8 M Pa
4. 16 M Pa
