It would be the controlled variable, which is a baseline to compare your other variables too.
Hope this helps!
Has to be the below money that has to do with the upper left corner plus the root
V1 = 30L, P1 = 200mmHg, T1 = 10C
V2 = ??, P2 = 300mmHg, T2 = 25C
Use combined gas law:
P1V1/T1 = P2V2/T2
V2 = P1V1T2/P2T1
V2 = (200)(30)(25)/(300)(10)
V2 = 150,000/3,000 = 50 L
If my memory serves me well, each period in the periodic table corresponds to a principal energy level. I think it's correct because periods are the horizontal rows and when you go down you always add <span> one to the principal energy level. Hope it is clear. Good luck!</span>
Solution is here,
for initial case,
temperature(T1)=70°C=70+ 273=343K
vloume( V1) =45 L
for final case,
temperature( T2)=?
volume(V2)= 91.3 L
at constant pressure,
V1/V2 = T1/T2
or, 45/91.3 = 343/ T2
or, T2= (343×91.3)/45
or, T2=695.9 K = (695.9-273)°C=422.9°C
