Question

Which law states that " product of volume and pressure at constant temperature is constant for a dry gas of given mass"
A. Charles’s law
B. Boyle’s law
C. Henry’s law
D. Dalton’s law

Answer 1

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.

Answer 2

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.
