Gas Volume Calculation based on Temperature Change
Explanation:
Charles's Law states that the volume of a gas is directly proportional to its temperature, assuming constant pressure.
The formula for Charles's Law is:
V1/T1 = V2/T2
Where:
V1 = initial volume (litres)
T1 = initial temperature (Kelvin)
V2 = final volume (litres)
T2 = final temperature (Kelvin)
Given data:
T1 = 275K, T2 = 400K, V2 = 5.82L
Using the formula:
V1/275 = 5.82/400
400 × V1 = 275 × 5.82
400V1 = 1601.5
V1 = 1601.5 ÷ 400
V1 = 4.00 L
Therefore, the volume of the gas before it is heated is 4.00 L.
