Acompressed gas cylinder containing 1.50 mol methane has a volume of 3.30 l. what pressure does the methane exert on the walls of the cylinder if its temperature is 25°c?

P=11.126 atm

Explanation:

We are given that a compressed gas cylinder containing 1.50 mol methane

Volume of methane in a gas cylinder =3.3 L

Temperature =

We have to find the pressure exert by gas on cylinder

Using ideal gas equation

PV =nRT

Where R= gas constant=0.0821 L-atm/K mol

Substitute all given values

Then we get

P=11.126 atm

Hence, the pressure exert by the gas on cylinder =11.126 atm

the results is a decrease in air temperature with an increase of altitude.

explanation:

no. dot product   =0 when vecs at right angles
