The gas law in which the pressure is kept constant is known as:
- A
Boyle’s Law
- B
Charles’s Law
- C
Dalton’s Law
- D
Graham’s Law
Charles’s Law – Correct. Charles’s Law states that at constant pressure, the volume of a gas is directly proportional to its temperature (V/T = constant).
Boyle’s Law – Incorrect. Boyle’s Law states that at constant temperature, the pressure and volume of a gas are inversely related (PV = constant).
Charles’s Law – Correct. Charles’s Law states that at constant pressure, the volume of a gas is directly proportional to its temperature (V/T = constant).
Dalton’s Law – Incorrect. Dalton’s Law deals with partial pressures of gases in a mixture.
Graham’s Law – Incorrect. Graham’s Law describes the rate of diffusion of gases, not pressure-volume relationships.
