Question

A sealed balloon is filled with 2.20 liters of Helium gas at 20.0° C. If the pressure does not change, what is the temperature when the balloon expands to a volume of 2.60 liters?

16.9° C
23.6° C
25.1° C
73.3° C

Answer 1

Do u know combined gas law ?

Answer 2

The ratio between the pressure-volume product and the temperature of a system remains constant. where: P is the pressure.

Answer 3

\(\huge\sf PV=nRT\)

Answer 4

if pressure is constant then
\(\huge\sf V \propto T\)

Answer 5

or

\(\huge\sf \frac{V_1}{V_2}=\frac{T_1}{T_2}\)

Answer 6

now can u find the correct answer ?

Answer 7

ya just let me work it out

Answer 8

???

Answer 9

i got 73.3

Answer 10
