Textbook Question
Chapter 5, Problem 165CP
You have a helium balloon at 1.00 atm and 25°C. Youwant to make a hot-air balloon with the same volumeand same lift as the helium balloon. Assume air is 79.0%nitrogen and 21.0% oxygen by volume. The “lift” of aballoon is given by the difference between the mass ofair displaced by the balloon and the mass of gas insidethe balloon.
a. Will the temperature in the hot-air balloon have tobe higher or lower than 25°C? Explain.
b. Calculate the temperature of the air required for thehot-air balloon to provide the same lift as thehelium balloon at 1.00 atm and 25°C. Assumeatmospheric conditions are 1.00 atm and 25°C.

Edit the reaction by drawing all steps in the appropriate boxes and connecting them with reaction arrows. Add charges where needed. Electron-flow arrows should start on the
electron(s) of an atom or a bond and should end on an atom, bond, or location where a new bond should be created.
