Question

A sample of gas in a balloon has an initial temperature of 15 °C and a volume of 1.31x103 L. If the temperature changes to 72 °C and there is no change of pressure or amount of gas, what is the new volume, ½ , of the gas? Express your answer with the appropriate units. 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: (Figure 1) View Available Hint(s) Ti T2 x.10n ½= | Value Units Figure 1 of 1 SubmitP X Incorrect, Try Again; no points deducted Not quite. Check through your calculations; you may have made a rounding error or used the wrong number of significant figures. Part B What Celsius temperature, T2, is required to change the volume of the gas sample in Part A (T-15?C, Vi-1.31x103 L ) to a volume of 2.62x103 L Assume no change in pressure or the amount of gas in the balloon. Express your answer with the appropriate units. Lower temperature Smaller volume Higher temperature Larger volume View Available Hint(s)
