Unless they explicitly state a number of significant figures,
you should adopt the number of significant figures of the values quoted in the question.
In this case 3.
Note that trailing zeros become important, thus (for example) 1.6 should be quoted as 1.60
I am not sure where the ln(4) arrives from in part (a)
27.6/3.9 is not equal to 4.
do we have a typo? (p2=6.9 perhaps). |

Yes, it is indeed 6.9 bar. Thanks for that.

Talking about convention, it's been taught to us (in my case by two universities now) that rounding off anything but the final answer is heavily discouraged especially when it comes to exponents and logarithms.

But is my solution for Work (nf and sf) correct, regardless of significant figures?
