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.
