Question

A balloon is filled with 500mL of helium at a temp of 27C and 75mmHg. What volume in mL will it have when it reaches an altitude where the temp is -33C and the pressure is 0.65atm?

Answer 1

The answer to your question is: V = 60.3 ml

Step-by-step explanation:

Data

V1 = 500 ml

T1 = 27°C = 300°K

P1 = 75 mmHg = 0.098 atm

V2 = ?

T2 = - 33°C = 240°K

P2 = 0.65 atm

Formula

`(P1V1)/(T1)  = (P2V2)/(T2)`

`V2 = (P1V1T2)/(T1P2)`

`V2 = ((0.098)(500)(240))/((300)(0.65)) \`

`V2 = (11769)/(195)`

V2 = 60.3 ml
