A balloon has a volume of 4.65 L at 35.0°C. The balloon is released into the atmosphere.

What is the temperature of the balloon's new location if the volume of balloon decreases to 4.15 L?

A gas-filled weather balloon with a volume of 56.0 L is held at ground level, where the atmospheric pressure is 768 mmHg and the temperature is 20.2 °C. The balloon is released and rises to an altitude where the pressure is 0.0511 bar and the temperature is –4.66 °C. Calculate the weather balloon's volume at the higher altitude.

A weather balloon is released at sea level (P=1.00 atm, T = 298 K, V = 25 L). Assuming no loss of gas as the balloon rises, determine the pressure in the upper atmosphere when the temperature is 255K and the volume has increased by 15% over what the volume was at sea level.
