At a festival, spherical balloons with a radius of 170, cm are to be inflated with hot air and released. The air at the festival will have a temperature of 25 °C and must be heated to 100 °C to make the balloons float. 1,00 kg of propane (C,H,) fuel are available to be burned to heat the air. Calculate the maximum number of balloons that can be inflated with hot air. Here are some data you may find useful: Specific heat capacity of air: Density of air at 100 °C: Density of propone at 100 "C: G 1.009 0.946 1.440 J 8ºC. kg 3 Formation enthalpy of propane at 25 "C:-103.8 m LJ mol Any other data you need should be taken from the ALEKS Data resource.
