The balloon ascends to an altitude of 3.00x 103 meters, where the pressure is 865 mbar. What is the volume of the helium in the balloon at the higher altitude? Assume that the temperature of the gas in the balloon does not change in the ascent. 1.544 > 2nd attempt 04:20 > + VIEW SOLUTION SUBMIT ANSWER

Explanation / Answer

V1 = 4.7 L

P = 992 mbar

P = 865 mbar

find volume at this height if T = constant

P1*V1 = P2*V2

4.70 L * 992 mbar = V2 * 865 mbar

V2 = 4.7*992/865

V2 = 5.390 Liters, since P decreases, V must increase
