A volume of15.6 litersground level, tem26Celsius and the pressure is 1.01 atm. It rises to an altitude where the temp is -10.3 Celsius, and the pressure is 0.10 atm. What is the volume of the balloon?

Answer 1

Combined gas law:

P1V1/T1 = P2V2/T2

P1 =1.01 atm

V1 = 15.6 L

T1 = 26C + 273 = 299K

P2 = 0.10 atm

V2 = ?

T2 = -10.3C + 273 = 262.7K

Plug these values into the combined gas law equation (see above) and solve for V2.
