I think the answer is Dust. Moons and stars definitely don't seem likely and dark particles, I am not even sure what those are. But I have seen rings on other planets before. Hope this helps. :)

A helium weather balloon is filled to a volume of 219 m3 on the ground, where the pressure is 754 torr and the temperature is 29

Answer:

$V_2 = 606.9 m^3$

Explanation:

By ideal gas equation law we know that

PV = nRT

now we know that when balloon rises to certain level then the number of moles will remains same

so we can say

$n_1 = n_2$

$\frac{P_1V_1}{RT_1} = \frac{P_2V_2}{RT_2}$

now plug in all data to find the final volume of the balloon

$\frac{754\times 219}{R(298)} = \frac{210 \times V_2}{R(230)}$

$V_2 = \frac{230\times 754 \times 219}{210 \times 298}$

$V_2 = 606.9 m^3$
