At a festival, spherical balloons with a radius of are to be inflated with hot air and released. The air at the festival will have a temperature of and must be heated to to make the balloons float. of propane 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 : Density of propane at : Formation enthalpy of propane at : Any other data you need should be taken from the ALEKS Data resource.
