Question

(c) A helium-filled weather balloon is held at ground level. The volume of the balloon is 4800 m3

.

The pressure of the helium is 98 kPa.

The balloon is released and rises to a height where the volume of the balloon is 7200 m3

.

(i) Calculate the new pressure of the helium. Assume that the temperature stays constant.

Answer 1

Hey mate ^_^

Answer:

Here,

$P1 = 98000$

$P2 = 7200$

$V1 = 4800$

$V2 =?$

Now,

$P1V1 = P2V2$

$98,000 × 4800 = 7200 × V2$

$V2 = \frac{98000 \times 4800}{7200}$

$V2 = 65,333.3$

Therefore,

$Pressure = 65,333.3 pa$
