For MCQ 16 isn’t the answer closer to 170kPa since the actual answer is 166666.6667 which actually rounds of to 170kPa. I know the answer in MS is b but I don’t think it’s right
nope, she solved it wrong i think. They asked for “change in pressure”. so ur supposed to get “P2-P1”. P1= 100kPa which is already given.. For P2,, use the same formula but V2= (25-15) not just 15 since they said it decreased by 15. P2=(100*25)/(25-15),,, P2= 250kPa thennn, P2-P1= 250-100 = 150 kPa i hope u understand
Yes you are correct, it should’ve been C but the marking scheme is B. If the marking scheme is incorrect you will get the mark regardless of what your answer is
its right cause the v2 is 10 as the v1 is reduced by 15, so 25-15 is 10 ; 25*100=10x which is 250kpa and they r asking the change in pressure so 250-100 is 150kpa

in exercise 40 she stopped talking in english
Honestly when you are searching for the answer and can't understand what she says is the most annoying part
Check The MS
