Gas Law Problem: Volume of Propane Calculation
What is the new volume of propane when a 2000 L fuel tank filled with propane at 21ᵒ C is cooled to 9ᵒ C?
a. 857.14 L
b. 1000 L
c. 1200 L
Answer:
The new volume of propane is 857.14 L.
In order to find the new volume of propane when the tank is cooled from 21ᵒ C to 9ᵒ C, we can use the idea of Charles's Law, which states that the volume of a gas is directly proportional to its temperature.
We can use the formula: V2 = V1 * (T2/T1), where V1 is the initial volume, T1 is the initial temperature, V2 is the final volume, and T2 is the final temperature.
Plugging in the values, V1 = 2000 L, T1 = 21ᵒ C, T2 = 9ᵒ C, we can calculate:
V2 = 2000 L * (9/21) = 857.14 L.
