0.16 mol of argon gas is admitted to an evacuated 70 cm^3 container at 30°c. the gas then undergoes an isothermal expansion to a volume of 400 cm^3 .what is the final pressure of the gas?

The final pressure of the gas is 9.94 atm.

Explanation:

Given that,

Weight of argon = 0.16 mol

Initial volume = 70 cm³

Angle = 30°C

Final volume = 400 cm³

We need to calculate the initial pressure of gas

Using equation of ideal gas

Where, P = pressure

R = gas constant

T = temperature

Put the value in the equation

We need to calculate the final temperature

Using relation pressure and volume

Hence, The final pressure of the gas is 9.94 atm.

the ima (higher than 1m) will be greater than the ima with the height of 1m.
