A very Bexible helium-filed baloon 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 760 mmHg The balloon ascends to an altitude of 20 km where the pressure is 76 0 mmHg and the temperature is -50 C What is the new volume, V2. of the balloon in fners, assuming it doesnt break or leak? Express your answer with the appropriate units.

Explanation / Answer

1. Here Here initial pressure (p1) is 760 mmHg initial Volume (v1) is 5 L initial temperature (t1) is 20 degree C i.e 293 K

Final pressure (p2) is 76 mmHg final Volume (v2) is to be known and final temperature (t2) is -50 degree C i.e 223 K

Hence by using p1v1/t1 = p2v2/t2 we can get final Volume

760*5/293 = 76*v2/223

v2 = 50*293/223

v2 = 65.7 litres

2.

Here initial pressure (p1) is 365 mmHg initial Volume (v1) is 4 L initial temperature (t1) is 20 degree C i.e 293 K

Final pressure (p2) is to be known final Volume (v2) is 2.70 L and final temperature (t2) is 40 degree C i.e 313 K

Hence by using p1v1/t1 = p2v2/t2 we can get final pressure

365*4/293 = p2*2.7/313

p2= 1460*313/293*2.7

p2 = 577.65 mmHg
