A lightweight weather-collecting sensor is attached to a 2.50-L balloon. The balloon is released on a day when the temperature is 23.4°C and the atmospheric pressure is 1.35 x 105 Pa. The balloon will collect data until it reaches the stratosphere.
(a) The weather sensor measures a temperature of –28.2°C and an atmospheric pressure of 285 Pa. What is the volume of the balloon?
(b) Given the change in the volume of the balloon as it reaches the stratosphere, should the balloon be fully inflated when released from the ground?
