Question

The air in a hot-air balloon is heated to make the balloon rise.

The size of gas molecules increases with temperature.

The pressure inside the balloon decreases and the balloon rises to equilibrate with the atmospheric pressure.

The attractive forces between the particles of the gas inside the can become stronger.

The particles spread farther apart and the density of air in the balloon becomes less than that of the atmosphere

15) (5 pts) Most people have seen either an actual hot air balloon or a picture of a hot air balloon. A burner at the base of the balloon is used to heat up the air in the balloon, making it expand and become less dense than the air outside the balloon. Thus the balloon floats. What is the pressure inside the balloon? Is it the same as, greater than, or less than the pressure outside the balloon, and how...

In Reno, the balloon launches (just barely) with 4 people on board. The next day , the balloon goes to Sacramento to launch with the same load and same temperatures (inside and outside the balloon). Will the balloon launch(will it rise up?) if yes, then how much extra load can they carry...
