the volume of a gas varies directly with its temperature and inversely with the pressure. if the volume of a certain gas is 10 cubic feet at a temperature of 300 k and a pressure of 30 pounds per square inch, what is the volume of the same gas at 280 k when the pressure is 20 pounds per square inch?

Sagot :

Therefore the volume of the gas is 14cubic feet.

What is the gas law?

The equation of state of an ideal gas, often known as the general gas equation, is the ideal gas law. Even though it has a number of restrictions, it is a good approximation of the behavior of various gases under a variety of situations. rules relating to gases, which link a gas's volume, pressure, and temperature. In accordance with Boyle's law, which bears Robert Boyle's name, a gas's pressure P and volume V vary inversely at constant temperature. PV = k, where k is a constant, is the formula for this relationship. As the pressure lowers, the gas volume rises according to Boyle's Law. According to Charles' Law, as a gas's temperature rises, its volume expands. We also know from Avogadro's Law that as gas concentration rises, so does its volume.

The volume of a gas varies directly with its temperature and inversely with the pressure.

V ∝ T/P

V= Volume of the gas at constant mass

T= Temperature at constant mass

P= pressure at constant mass

[tex]V_{1} /V_{2}[/tex] = [tex]\frac{T_{1}/ T_{2}}{P_{1}/ P_{2}}[/tex]

At constant mass, the volume of a certain gas is 10 cubic feet and a pressure of 30 pound per square inch at a temperature 300 k.

[tex]V_{2}[/tex] = 14 cubic feet
