Homework Statement
A man wants to go on a hot air balloon trip, and wants to build a balloon with a capacity of 10,000 m^3. The envelope and the balloon have a combined mass of 250 kg. His luggage would be 800 kg. Assume that the ambient air is at a temperature of 20 degrees Celsius. What must the temperature of the air inside the balloon be to provide the required lift?
Homework Equations
The ideal gas law: P = ρRT
Archimedes' Principle: density of object/density of fluid = weight/weight-apparent immersed weight
The Attempt at a Solution
My lab group is not entirely sure where to start with this. We feel that these two formulas will be useful simply because when we examine other similar problems, they come up, but we aren't sure where to start or how to get our information into these formulas so they will work properly. Can we get some help on where to even begin with this problem?
