Gas Volume Calculation using Charles Law
Problem:
3.50 liters of a gas at 727.0 K will occupy how many liters at 153.0 K?
Question:
How can we determine the volume of gas at 153.0 K using Charles Law?
Answer:
0.737 L
Explanation:
Charles law states for a fixed amount of gas, volume of the gas is directly proportional to the absolute temperature of the gas at constant pressure.
We can use the following equation:
V1/T1 = V2/T2
where V1 is volume and T1 is temperature at first instance.
V2 is volume and T2 is temperature at the second instance.
Substituting the values:
3.50 L / 727.0 K = V2 / 153.0 K
V2 = 0.737 L
Therefore, the new volume at 153.0 K is 0.737 L.
