- Problem 7 Hot air balloons make use of Archimedes' principle, and are the oldest flying machines. They make use of the fact that the density of air depends on the temperature in such a way kg 1.2 m3 0.9 kg m3. that P68° F and p250° F = If a hot air balloon has a total volume of 3,000 m³, how much weight can it support if the air outside is 68°F and the air inside the balloon is 250° F? *Why are most ballon launches done in the morning?*Example 1: Find the height h?

T= 90°C Sat. liquid 70.183 kPA 904Current Attempt in Progress The diffusion constant for the amino acid glycine in water is 1.06 x 10-9 m²/s. In a 2.0-cm-long tube with a cross-sectional area of 1.3 x 10-4 m², the mass rate of diffusion is m/t = 4.2 x 10-14 kg/s, because the glycine concentration is maintained at a value of 9.3 × 10-3 kg/m³ at one end of the tube and at a lower value at the other end. What is the lower concentration? C₁= i
