Question

A sample of argon gas has a volume of 6 liters at a temperature of 7*C. What volume does the gas occupy at 147*C?

Answer 1

9L

Explanation:

Given parameters:

Volume of gas = 6L

Initial Temperature = 7°C to kelvin = 273 + 7 = 280K

Final temperature = 147°C to kelvin = 273 + 147 = 420K

Unknown:

Final gas volume = ?

Solution:

To solve this problem, we are going to use Charles's law. Charles's law states that "the volume of a fixed mass of a gas varies directly as its absolute temperature if the pressure is constant".

 Mathematically;

   $\frac{Initial volume }{Initial temperature } = \frac{final volume }{final temperature}$

Input the parameters;

   $\frac{6}{280} = \frac{V}{420}$

  V = $\frac{6 x 420}{280}$ = 9L
