A gas which obeys Charles’ law exactly has a volume of 283cm3 at 10oC. What is its volume at 30oC?
Question 1 Report
A gas which obeys Charles’ law exactly has a volume of 283cm3 at 10oC. What is its volume at 30oC?
Answer Details
Charles' Law states that, for a given mass of gas at constant pressure, the volume of the gas is directly proportional to its temperature measured in Kelvin. So we can use the formula V1/T1 = V2/T2, where V1 and T1 are the initial volume and temperature, and V2 and T2 are the final volume and temperature.
Converting the temperatures to Kelvin, we have T1 = 283K and T2 = 303K. We know that the gas obeys Charles' law exactly, so we can use the formula to find the final volume:
V2 = (V1/T1) x T2
V2 = (283/283) x 303
V2 = 303
Therefore, the final volume of the gas at 30°C is 303cm^3. So the correct option is 303cm^3.
