A) 0.188 L
B) 0.333 L
C) 3.00 L
D) 5.33 L

According to Charles's Law, at constant pressure, the volume of a gas is directly proportional to its temperature in Kelvin. This means that V1/T1 = V2/T2.

We can set up the equation as (4.00 L)/(400 K) = V2/300 K and solve for V2:

V2 = (4.00 L)*(300 K)/(400 K) = 3.00 L

Therefore, the new volume of the gas sample is 3.00 L. Choice C is the correct answer.

At Constant Pressure, the Temperature of a 4
