A) A balloon filled with 2.00 L of helium initially at 1.55 atm of pressure rises into the atmosphere. When the surrounding pressure reaches 490. mmHg, the balloon will burst. If 1 atm = 760. mmHg, what volume will the balloon occupy in the instant before it bursts?
Express your answer with the appropriate units.
B) What Celsius temperature, T2, is required to change the volume of the gas sample in Part A (T1 = 13 °C , V1= 1970 L ) to a volume of 3940 L ? Assume no change in pressure or the amount of gas in the balloon.
Express your answer with the appropriate units.
