Weather balloons carry instruments that can gather data about Earth’s atmosphere. On the ground, a weather balloon has a volume of 250. L, a pressure of 755 mmHg, and a temperature of 25.0°C. As the balloon ascends into the atmosphere, the temperature decreases to 22.0°C and the pressure changes to 710. mmHg. What is the new volume of the weather balloon? Type in your answer using the correct number of significant figures. L
