Answer:
h = 4 in
Explanation:
GIVEN DATA:
volume of tin
we know that
volume of cylinder is
so,
construct formula for surface area
minimize the function wrt h
solving for h we have
we kow so
h = 4 in
Intially, we have:
Pressure P1 = 400KPa
Temperature T1= 110Kelvin
When,
Temperature T2= 235 Kelvin
Pressure P2= ?
We have gas equation:
PV= nRT
P/T= nR/V
Considering nR/T as constant, we have:
P1/T1 = P2/T2
400/110= P2/235
P2= 854.5 KPa
So the new temperature will be 854.5 KPa
