Initial pressure, P₁ = 120 kPa
Initial temperature, T₁ = 0˚C = 273 K
We need to find the final temperature when the pressure is 80 kPa.

79470.2mL
Explanation:
Given:
Volume = 21gallons
problem, convert to milliliters;
gallons to milliliters
1 liter = 1.057 quarts
1 gallon = 4 quarts
we can simply solve this by establishing and using a conversion factor of 1 ;
1 gallon = 4 quarts
1.057 quarts = 1 liter
0.001L = 1mL
21gallons x
= 79470.2mL
we say;
From; 
1gallon = 3784.2mL
