At a festival, spherical balloons with a radius of
110.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.
3.00kg
of butane
C4H10
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: 1.009J·g°C
Density of air at 100°C: 0.946kgm3
Density of butane at 100°C: 1.898kgm3
Formation enthalpy of butane at
25°C: ?125.7kJmol
