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.)

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
