Which of the following relationships correctly depict the relationship between pressure and volume for a fixed amount of gas at
Dovator [93]

Answer:

Non of the option applies

Explanation:

Gases may be assumed to obey the ideal gas law, which states that, for pressure P, volume V, number of moles n, and temperature T,

PV = nRT.

where  R  is the gas constant, and n is the number of mole of gas

If the temperature is held constant, we obtain a simplified version called Boyle's Law, and if the pressure is held constant, we obtain Charles' Law.

Boyle's law:

Boyle's law states that the volume of a given mass of gas is inversely proportional to is pressure, provided that the temperature remains constant.

Mathematically,

P ∝ I/V

∴ PV ∝ 1

From the above mathematical expression, it shows that PV is a constant and does not change with pressure or volume.

∴ non of the options applies
