The answer is correct. But, be careful in the work. In your work, you are using 1000kg when you mean 1000g or 1kg. You knew what you meant, but you might lose some points in the work.

No, you didn't work it right. Check the units in your work, your answer comes out as kg-second. Is that a force? You can do better than this.

**Physics please check**

since work is done on the gas, the value of work has to be negative. so you would do 2531 + 1101 instead

your formula is correct. however since it says the work is done on the system work has to be negative so you would do 2531-(-1101) or 2531 + 1101. That should give u the right answer
