How much work is done (in L*atm) by a gas that expands from 7.6 liters to 24 liters against an external pressure of 3.4 atm?

The work done by the gas is 55.76 L*atm.

Explanation:

The work can be found as follows:

    (1)

Where:

p: is the pressure = 3.4 atm

V(f): is the final volume = 24 L

V(i): is the initial volume = 7.6 L

By replacing the above values into equation (1) we have:

Therefore, the work done by the gas is 55.76 L*atm.

I hope it helps you!

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
