The voluem of a certain mas of helium500ml at400k if he hav to change the volium of this gas to 40cm3 what change sheid br brought about in temparater
Answered by Damon
a mL IS a cm^3

p v = n R T

P1 V1/T1 = P2 V2/T2 if n and R constant

I guess you want the pressure to be the same?

then
V1/T1 = V2/T2
so
T2 = (V2/V1)T1
T2 = (40/500)400
T2 = 32 k very cold
