A sphere balloon with 30 cm in radius is released from the ground, 300 K and 101.325 kPa. The balloon is charged with Helium at 1 atm (absolute), thus creating buoyant force for balloon to rise. The radius of the balloon does not change, and the mass of balloon is 0.1 kg, except the mass of Helium inside. The atmosphere can be assumed to be isothermal at 300 K with air (molecular weight = 29 kg/kmol). a. Calculate the mass of Helium inside the balloon and the densities of Helium and air at 101.324 kPa and 300 K by using ideal gas law. b. Calculate the maximum velocity of the balloon during the rise and find out the altitude of maximum velocity. Include a figure showing the changes of acceleration and velocity as a function of altitude. (Hint) a = VV, where a is the acceleration, V is the velocity, and z is the altitidue. dv dz'
A piston-cylinder contains gas initially at 3500 kPaa with a volume of 0.03 m². The gas is compressed during a process where pV¹25= C to a pressure of 8500 kPaa. The heat transfer from the gas is 2.5 kJ. Determine the change in internal energy, neglecting changes in kinetic and potential energies. [Ans. 141.9 kJ]

In the 1970s cartoon The Super Friends, the Wonder Twins helped Superman and others fight crime. One of the Wonder Twins was Zan, who was able to take on the form of H2O in its various phases (ice, liquid water, water vapor). After taking a physics class, he decides to conduct a little experiment by turning into an ice igloo in the park on a hot day. (a) If his total mass as an igloo is 64.50 kg and he starts with a temperature of −13.50°C, how much heat must flow into him to completely melt his body? J(b) He continues absorbing energy up to the point where he would start to vaporize (100.0°C). How much more heat is required to raise his temperature to the vaporization point? J(c) How much more heat is required to turn him into water vapor at 100.0°C? J(d) If we model the water vapor molecules making up his body as having only six degrees of freedom, what is the average kinetic energy of one of the water vapor molecules that make up Zan? (Consider the case when Zan is water vapor at…
A quantity of a certain perfect gas is compressed from an initial state of 0.085 mt bar to a final state of 0.033 m. 3.8 bar. The specific heat at constant volume is 0.724 k/kg K. and the specific heat at constant pressure is 1.02 k/kg K. The observed temperature rise is 122 K.
