Consider an ideal gas enclosed in a 1.00 L container at an internal pressure of 18.0 atm. Calculate the work, w , if the gas expands against a constant external pressure of 1.00 atm to a final volume of 18.0 L.

Respuesta :

Answer:

-32821.2 J (negative sign implies that work is done by the system)

Explanation:

The expression for the calculation of work done is shown below as:

[tex]w=-P\times \Delta V[/tex]

Where, P is the pressure

[tex]\Delta V[/tex] is the change in volume

From the question,  

[tex]\Delta V[/tex] = 18.0 - 1.00 L = 18.0 L

P = 18.0 atm

[tex]w=-18.0\times18.0\ atmL[/tex]

Also, 1 atmL = 101.3 J

So,  

[tex]w=-18.0\times 18.0\times 101.3\ J=-32821.2\ J[/tex] (negative sign implies that work is done by the system)
