The density of air at 20 degree celcius is 1.204 kg/m3. The density at temperature 100 degree celcius is 0.9467 kg/m3. If an average size hot air balloon envelopes a volume of 2200 m3, how much weight can it lift (including the balloon itself)? a. 5.55 kN b. 11.1 kN c. 20.4 kN d. 26.0 kN

I put air in the tires of my car during the summer, while it was 28.8 °C outside (about 83.8 °F). My tires say to fill them to a pressure of 203,000 Pa.   Boltzmann's constant is 1.38 * 10 ^ - 23 * J / K   A) If my tires have a volume of 0.0100 m³, how many air molecules are in the tire?   N = molecules   B) These tires go all summer without losing any air, however come fall the temperature drops down to 8.65 °C (about 47.6 °F). Assuming the volume doesn't change (because it doesn't) what is the new pressure in my tires?   P=
