Q1: A weather balloon with a volume of 201 L is launched at 20.0°C at sea level, where the atmospheric pressure is 1.00 atm. The balloon rises to an altitude of 2.00 × 10^4 m, where atmospheric pressure is 57.0 mmHg and the temperature is 210.0 K. What is the volume of the balloon at 2.00 × 10^4 m?
Q2: A gas in a sealed but flexible container has been heated to 41.0°C. At this temperature, it has a pressure of 2.73 atm and a volume of 45.5 L. If the gas was initially at 23.0°C and 911.0 torr, what was its initial volume in liters?
