You happen to come across a piece of metal that has a density of p = 7.43 g/cm³ when the temperature is To = 45.0 °C. If the metal is cooled to a temperature of T = 0.00 °C, does the density change? No, because as the volume changes so does the mass. No, density does not depend on temperature. Yes, since the metal contracts and the mass is constant, the density will increase. Yes, the density will decrease since the volume changes. Calculate the density of the piece of metal at this temperature, p1. The coefficient of volume expansion for this piece of metal is ß = 8.43 x 10-s 1°°C.
In this problem you will consider the effect that thermal expansion due to temperature will have on Archimedes' principle.

A hot air balloon uses the principle of buoyancy to create lift. By making the air inside the balloon less dense then the surrounding air, the balloon is able to lift objects many times its own weight. A large hot air balloon has a maximum balloon volume of 2090 m3. a. If the air temperature in the balloon is 54 °C, how much additional mass, in kilograms, can the balloon lift? Assume the molar mass of air is 28.97 g/mol, the air density is 1.20 kg/m3, and the air pressure is 1 atm.
