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
