15 grams of ice at −15°C is to be changed to steam at 110°C. The specific heat of both ice and steam is 0.5 cal/g · C°. The heat of fusion is 80 cal/g and the heat of vaporization is 540 cal/g. The specific heat of water is 1.00 cal/g · K. The entire process requires
A 0.35-kg block oscillates on the end of the spring with a spring constant of 277 N/m. If the system has an energy of 4.0 J, then the amplitude of the oscillation is:
One gram of water (1 cm3) becomes 875 cm3 of steam when boiled at a constant pressure of 1 atm (1.013 x 105 Pa). The heat of vaporization at this pressure is Lv = 2.256 x 106 J/kg. Compute a) the heat absorbed by the water b) the work done by the water when it vaporizes and c) its increase in internal energy.
A gas is compressed from an initial volume of 0.42 m3 to a final volume of 0.12 m3. During the quasi-equilibrium process, the pressure changes with volume according to the relation P = aV 1 b, where a = 21200 kPa/m3 and b = 600 kPa. Calculate the work done during this process (a) by plotting the process on a P-V diagram and finding the area under the process curve and (b) by performing the necessary integrations.
