MCQ. If car tires are hot, pressure of gas molecules in them would be

  1. high
  2. low
  3. same as before heating
  4. may be high or low

A

MCQ. Volume of gas is

  1. directly proportional to temperature
  2. inversely proportional to temperature
  3. directly proportional to friction
  4. inversely proportional to heat

A

MCQ. If air at a pressure of 1 MPa is compressed such that new volume of air is one quarter of its initial volume, then new pressure of air is

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

D

MCQ. In an aquarium, air bubble at bottom has a volume = 0.5 mm³. What would be size of bubble at top if height of water level is = 1 m. (density of water = 1000 kg ⁄ m³, atmospheric pressure = 1 × 105 Pa, gravitational acceleration = 10 m s-1²)

  1. 0.5 mm³
  2. 0.55 mm³
  3. 0.6 mm³
  4. 0.65 mm³

B

MCQ. As volume is inversely proportional to pressure, we can conclude that

  1. p1V2 = p2V1
  2. p2/V2 = p1V1
  3. p1V1 = p2V2
  4. p1V1 = p2/V2
