Question 33
Gas LawsIf the volume of a fixed mass of a gas is kept constant, the pressure of the gas
- A.is inversely proportional to its centigrade temperature
- B.is inversely proportional to its absolute temperature
- C.is directly proportional to its centigrade temperature
- D.is directly proportional to its absolute temperature
- E.remains constant also.
Show the answer and explanation
Answer: D (is directly proportional to its absolute temperature)
Explanation
The pressure law: at constant volume, p ∝ T where T is the absolute (kelvin) temperature.
