Question

A hot air balloon song with its cargo has a mass of 4.0 * 10^5 kg. And it holds 7.0 * 10^5 m^3 of hot air. It is floating at a constant height in air with a density of 1.29 kg/m^3. What is the density of the hot air in the balloon

Expert Solution

Step 1

Let us consider the buyoant on the balloon is, F_b= Density of air outside the balloon (D)× volume of the balloon(V) × acceleration due to gravity (g) = D×V×g.

Weight of the hot air inside the balloon, W_hot= Density of the hot air(D') × Volume of the balloon (V) × acceleration due to gravity (g)=D'×V×g.

The weight of the balloon is , W_balloon= mass of the balloon(M) × acceleration due to gravity(g)= M×g.
