A balloon originally had a volume of 0.439 L at 44°C and a pressure of 729 torr.To what temperature must the balloon be cooled to reduce its volume to 378 mL if the pressure remained constant?

Charles's law states that the volume of a gas is directly proportional to its temperature. So, if the pressure remains constant, the volume of the balloon will decrease as the temperature decreases. To find the temperature to which the balloon must be cooled, we can use the following equation:V1/T1 = V2/T2where V1 is the original volume, T1 is the original temperature, V2 is the new volume, and T2 is the new temperature.Plugging in the given values, we get:0.439 L / (44°C + 273) = 0.378 L / T2Solving for T2, we get:T2 = 38°C + 273 = 311 KTherefore, the balloon must be cooled to 38°C to reduce its volume to 378 mL.
