Question

nView?offset-next&kassignmentProblemiD-93602173; A very flexible helium-illed balloon is released from the ground into the air at 20 C. The initial volume of the balloon is 5.00 L and the pressure is 7 0 mmHg The balloon ascends to an altitude of 20 km where the pressure is 760 mm g and the temperature is 50. C What isthe new volume, V2, of the balloon in liters, assuming it doesn't break or leak? Express your answer with the appropriate units. View Available Hint(s) Part B Consider 4.70 L of a gas at 365 mmHg and 20 C If the new pressure. P inside the container? Assume no change in the amount of gas inside the cylinder Express your answer with the appropriate units. ew Available Hint(s)

Explanation / Answer

temperature T1 = 20 oC = 293 K

volume V1 = 5.00 L

pressure P1 = 760 mmHg

Pressure P2 = 76.0 mmHg

temperature T2 = - 50 oC = 223 K

P1 V1 / T1 = P2 V2 / T2

760 x 5 / 293 = 76 x V2 / 223

V2 = 38.1

volume = 38.1 L

part B)

volume V1 = 4.70 L

T1 = 293 K

P1 = 365 mmHg

V2 = 3.00 L

T2 = 307 K

365 x 4.70 / 293 = P2 x 3.00 / 307

P2 = 599

pressure = 599 mmHg
