Concept Practice-1. Why does blowing over hot soup cool the soup?2. Why are icebergs often surrounded by fog?3. Suppose a new liquid were discovered that is identical to water in every way except that it has a lower latent heat of fusion. Would it take a longer or shorter time to make ice out of this liquid in your freezer? Why?4. A great amount of water vapor changes phase to become water in the clouds that form a thunderstorm. Does this release thermal energy or absorb it? Explain.Quantitative Practice-5. Steam at 100C is added to ice at 0C. Find the temperature when the mass of steam is10 g and the mass of ice is 50 g. The specific heat of water is 4186 J/kgC, its latent heat of fusion is 3.33105 J/kg and its heat of vaporization is 2.2610 J/kg.6. In an insulated vessel, 250 g of ice at 0C is added to 600 g of water at 18C. How much ice remains when the system reaches equilibrium? Assume the heat of fusion of ice is 79.7 cal/g and its specific heat is 0.5 cal/gC. The heat of vaporization of water is 540 cal/g and its specific heat is 1 cal/gC.7. When a lead bullet hits a large solid target at high speed, its entire kinetic energy is converted into heat. For simplicity, assume that all that heat is concentrated in the bullet rather than the target. If the bullet's initial temperature is 15C, how fast would it have to move before the collision in order to have 30% of its mass melted after the collision? Lead has a melting temperature 327.3C, a specific heat of 128 J/kg K and latent heat of fusion 24500 J/kg.

NAME: Various thermodynamic Processes - Work Done by Gas 110 Five thermodynamic processes are illustrated below. All five processes are for the same ideal gas startif and the same initial pressure and temperature ( P, and To ). Each of the five distinctly different processes results in different final equilibrium states. The labels on each of the diagrams are to be interpreted as follows: A = adiabatic L = linear IT = isothermal IV = isovolumetric IB = isobaric Rank these processes from greatest to lease on the basis of the amount of work that is done by the gas. Positive work should be ranked higher than negative work. P. -.......... " Po Po Po 12 P 12 .. ..:. P. 12 A IV -. ............ Vo 2Vo Vo 2Vo Vo 2V P ......... ".= E......... ...."
