I only lost marks in the last question. Such bad luck. Was going to do that paper yesterday but didn't.

What went wrong?

 

[FLRNAB]

What went wrong?

I wrote 29.8 and 24.9 instead of 9.8 and 4.9
Technically they must be right because 29.8 is the maximum rise of the temperature.

I also halved the volumes because the invigilator said Time's up. Panic

Well it said rise so we had to write minus 20,and this was evident by the different box in the table,and yeah the volume one was tricky.

No I did write 9.8 and 4.9 first. Then I added the "2" and lost 2 marks. (Hope not)
