The pressure at 0°F would be 4.5psi
Explanation:
Given-
Pressure, P1 = 5psi
Temperature, T1 = 50°F
T2 = 0°F
P2 = ?
To convert Fahrenheit to Kelvin we have to apply the formula:
(x°F 32) X 5/9 + 273.15
So,
0°F = (0-32) X 5/9 + 273.15 = 255.372K
50°F = (50-32) X 5/9 + 273.15 = 283.15K
According to gas equation,
[tex]\frac{P1}{T1} = \frac{P2}{T2} \\\\\frac{5}{283.15} = \frac{P2}{255.372}\\\\P2 = \frac{(5) (255.372)}{(283.15)}\\ \\P2 = 4.5psi[/tex]
Therefore, the pressure at 0°F would be 4.5psi
