GUARANTEED 100 POINTS PLUS BRANLIEST, PLEASE ANSWER SOON! URGENT :( Part 1 - If the starting volume of a hot air balloon is 55,500 m^3 and the initial
temperature is 21 °C, what is the temperature inside the balloon is the final
volume is 74,000 m^3?

Part 2 - Explain why the volume of the balloon increases when temperature is increased in terms of average kinetic energy, collisions and volume. Explain how the balloon is actually able to lift off the ground in terms of density. (Density of hot air is 0.946 kg/m^3 and the density of normal ambient air is 1.2 kg/m^3.)
