7) A gas has a pressure of 2.5 atm and a volume of 300 Liters is compressed so it has a pressure of 5 atm, what is the compressed volume?

A gas has a volume of 152 Liters in a helium balloon at 25 degrees Celsius. as the balloon rises in the atmosphere the temperature drops to 18 degrees Celsius, what is the volume of the gas at the cooler temperature?
