A closed rigid tank with volume 3.2 m3 contains 182 kg of steam at pressure 40 bar. The tank is equipped with an alarm that will sound if pressure exceeds 80 bar. The tank is heated until the alarm sounds. Determine the state of state steam at that point. If the state is vapor/liquid mixture, report the mass fraction of the vapor.\

The air that we breath is made mostly of which gaseous molecule

Find the mass by adding the numbers from the three sliders

An insulated thermos contains 148 g of water at 72.7 ˚c. you put in a 11.7 g ice cube at 0.00 ˚c to form a system of ice + original water. the specific heat of liquid water is 4190 j/kg•k; and the heat of fusion of water is 333 kj/kg. what is the net entropy change of the system from then until the system reaches the final (equilibrium) temperature?
