Question

At a festival, spherical balloons with a radius of 220. 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. 2.00 number of balloons that can be inflated with hot air. of butane (C4H10) fuel are available to be burned to heat the air. Calculate the maximum Here are some data you may find useful: J Specific heat capacity of air: 1.009 kg Density of air at 100 °C: 0.946 m kg Density of butane at 100 °C: 1.898 3 m kJ Formation enthalpy of butane at 25 °C: -125.7 mol Any other data you need should be taken from the ALEKS Data resource.
