A weather balloon, filled with helium gas, is released from the ground at sea level. Initially, the volume of the balloon is 10 m³, the internal pressure is 101,325 Pa, and the temperature is 20°C. Upon reaching an altitude of 10 km, where the external pressure is 26,500 Pa and the temperature is -50°C, the balloon undergoes a gas transformation. Considering the constant mass of helium gas and neglecting the weight of the balloon, what is the volume of the weather balloon at the altitude of 10 km?a.
37.78 m³
b.
56.25 m³
c.
48.90 m³
d.
12.58 m³
e.
22.35 m³
