A fluid is contained in a cylinder by a spring-loaded, frictionless piston so that the pressure in the fluid is linear function of the volume (p = a + bV). The internal energy of the fluid is given by the following equation U = 34 + 3.15 pVwhere U is in kJ, p in kPa and V in cubic metre. If the fluid changes from an initial state of 173 kPa, 0.03 m3to a final state of 400 kPa, 0.06 m3, with no work other than that done on the piston, find the direction and magnitude of the work and heat transfer.

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'
