Question

A balloon contains a fixed amount of helium. If the initial conditions are 1.12 liters, 3.00 atmospheres, and 19 degrees Celsius, what will the final volume be when the balloon is exposed to 1.00 atmosphere pressure and 22 degrees Celsius?

0.370 L

0.377 L

2.90 L

3.39 L

Answer 1

@Google I believe its 3.39 L.

Answer 2

hmm

Answer 3

hold on gimme a minute

Answer 4

Okay (;

Answer 5

you know how to do the math on this question?

Answer 6

V1 = 1.12 L
P1 = 3 atm
T1 = 19 + 273 = 292 K
V2 = ?
P2 =1 atm
T2 = 22 + 273 = 295 k

P1V1/T1 = P2V2/T2
V2 = P1V1T2/P2T1 = (3)(1.12)(295)/(1)292) = 3.39 Liters
So my answer = (D) 3.39 L

Answer 7

\[3.00x1.12/ (19+273) = 1.00 x V2 / (22+273) \]

Answer 8

your answer is right but the math is kinda off

Answer 9

\[v2=3.93L \]

Answer 10

is correct

Answer 11

Okay, got ya.
