Abubble of helium gas has a volume of 0.650 cm3 near the bottom of a large aquarium where the pressure is 1.54 atm and the temperature is 12°c. determine the bubble’s volume upon rising near the top where the pressure is 1.01 atm and 16°c. assume that the number of moles of helium remains constant and that the helium is an ideal gas.

important equations and constants 1 atm = 760 torr = 760 mmhg = 101,325 pa

1ml = 1cm3

pv = nrt

p1v1 = p2v2

v1/t1 = v2/t2

v1/n1 = v2/n2

ptotal = p1 + p2 + p3 + ….

(p1v1)/(n1t1) = (p2v2)/(n2t2)
