Helium in the balloon is initially at 15°c and 550 kpa and cv = 3.12 kj/(kg-k) for helium. the balloon can be considered to be a rigid sphere with a radius of 25 m. (a) determine the mass of helium in the balloon, in kg. (b) as the balloon rises, the helium is heated by solar radiation to 300°c. the balloon will burst if the pressure in the balloon is greater than 1.1 mpa. will the balloon burst? why or why not? (c) what is the heat transfer to the balloon due to solar heating, in mj? (d) the air balloon company wants to reduce mass of the ball

Asubmarine has a "crush depth" (that is, the depth at which water pressure will crush the submarine) of 250 m. what is the approximate pressure (water plus atmospheric) at this depth? (recall that the density of seawater is 1025 kg/m3, g = 9.81 m/s2, and 1 kg/(ms2) = 1 pa = 9.8692 10-6 atm.) a. 34.8 atm b. 24.8 atm c. 25.8 atm d. 7.8 atm
