a sample of carbon dioxide gas at 311 k and 0.956 atm occupies a volume of 1.12 l. if the pressure of the gas is decreased, while at the same time it is heated to a higher temperature, the final gas volume

Respuesta :

The final volume will be larger than 1.12L.

What is ideal gas equation?

The equation of a hypothetical perfect gas's state is known as the ideal gas law. It has a number of limitations, but it is a good approximation of the behaviour of various gases under a variety of situations.

PV=nRT

Using ideal gas equation

V2= P1V1/T1 ×T2/P2

In this equation P2 is in denominator so when pressure is decreased V2 increases.

T2 is in numerator so when temperature increases V2 increases.

Overall V2 increases.

The final gas volume will increase

Define the ideal gas law.

The ideal gas law, also known as the perfect gas law, is a relationship between a gas's pressure P, volume V, and temperature T in the range of low pressures and high temperatures where the gas's molecules move virtually independently of one another.

The ideal gas law (PV = nRT) connects the macroscopic characteristics of ideal gases. An ideal gas is one in which the particles are both non-repellent and non-attractive to one another (have no volume).

PV = nRT

P1V1/T1 = P2V2/T2

From tis .pressure is directly proportional to volume

So if pressure is decreased, volume also decreases
