Question
Plus or minus Temperature and Volume Charles's law states that the volume of a gas is directly related to the absolute temperature when there is no change in the pressure or amount of gas: (Fiaure 1) V1/T1=V2/T2 Part A A sample of gas in a balloon has an initial temperature of 34 degree C and a volume of 2.00x10^3L. If the temperature changes to 75 degree C, and there is no change of pressure or amount of gas, what is the new volume, V2, of the gas? Express your answer with the appropriate units. V2= Value Units Part B What Celsius temperature, T2, is required to change the volume of the gas sample in Part A (T1 = 34 degree C, V1= 2.00x10^3 L ) to a volume of 4.00x 10^3L ? Assume no change in pressure or the amount of gas in the balloon. Express your answer with the appropriate units. T2 = Value UnitsExplanation / Answer
Answer:
a) V1/T1 = V2/T2
2*10-3/(273+34) = V2/(273+75)
V2 = 2.267*10-3 L
b) V1/T1 = V2/T2
T2 = V2*T1/ V1
T2 = 4*10-3*(273+34)/ 2*10-3L
= 614K = 3410C
