a light to be vaporizatio exchanger using 250 kPa steam of 90% quality. The heat losses to the surrounding air have been estimated to be 5% of the heat transferred from the condensing steam to the oil. If the steam condensate leaves at its saturation point, what mass of steam per hour will be used in the exchanger? For light oil, Snecific aravity- 0 88

Problem 2: The enthalpy of a system is given by the equation H = U + PV where U is the internal energy, P = pressure, and V = volume. In addition, the internal energy, U = Q + W where Q is the heat and W is the work. Suppose we want to find the rate of change in the enthalpy at constant pressure of 1.25 atm, what is the value when heat is absorbed by the system at a rate of 45 J/s and work is done by the system at a rate of 100 J/s when the change of volume is rated at 35 x 105 m/s? 1. What is the change in heat with respect to time? 2. What is the change in internal energy of the system with respect to time? 3. What is the change in enthalpy of the system with respect to time?

A metal spoon and a wooden spoon are left overnight in a room. Why do we feel colder when we touch the metal spoon than when we touch the wooden one? a. Since metals usually have a lower heat capacity than non-metals, the metal spoon loose more heat to the room and consequently has a lower temperature b. Metals release heat faster than non-metals because of their higher thermal conductivity c. This is merely psychological since we are conditioned to think of metals as “cold” d. Metals absorb heat faster than non-metals because of their higher thermal conductivity
