B. Boyle’s law
C. Henry’s law
D. Dalton’s law

Boyle's law (option B) states that " the product of volume and pressure at a constant temperature is constant for a dry gas of given mass."
• Boyle stated that pressure and volume of a gas are inversely proportional to each other, provided the temperature is kept constant.
• If the pressure on a gas increases, its volume decreases and vice-versa.
• Therefore, mathematically,
P ∝ 1 / V
Or, PV = k
where k is the proportionality constant.
• Therefore, Boyle stated that the product of pressure and volume of a gas is constant at a constant temperature.
B) Boyle's Law
Explanation:
Boyle's law states that the product of volume and pressure at constant temperature is constant for a dry gas of given mass.
The law can also be interpreted as the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature.
The mathematical representation of the Boyle's law is
P1V1 = P2V2
Where p is pressure and v is volume.
