In your experiment, you select one piece of metal and heat it to 100.0 °C, and then select a second piece of metal and cool it to -10.0 °C. Both pieces of metal are then placed in the beaker of water and the temperatures equilibrated. You want to select two pieces of metal to use such that the temperature changes the least, that is, the final temperature should be as near to 21.0 °C as possible. What piece of metal will you heat (choose its number)? What piece of metal will you cool (choose its number)? What is the final temperature of the water? Final temperature = °℃

1.22 In order to prevent frostbite to skiers on chair lifts, the weather report at most ski areas gives both an air temperature and the wind-chill temperature. The air temperature is measured with a thermometer that is not affected by the wind. However, the rate of heat loss from the skier increases with wind velocity, and the wind-chill temperature is the temperature that would result in the same rate of heat loss in still air as occurs at the measured air temperature with the existing wind. Suppose that the inner temperature of a 3-mm-thick layer of skin with a thermal conductivity of 0.35 W/m K is and the air temperature is . Under calm ambient conditions the heat transfer coefficient at the outer skin surface is about (see Table 1.4), but in a 40-mph wind it increases to . (a) If frostbite occurs when the skin temperature drops to about , do you advise the skier to wear a face mask? (b) What is the skin temperature drop due to the wind?

the question from thermodynamics Oxygen (molar mass 32 kg/kmol ) expands reversibly in a cylinder behind a piston at a constant pressure of 3 bar. The volume initially is 0.01 m3 and finally is 0.03 m3; the initial temperature is 18.97 0C. Calculate the mass of oxygen with the correct unit to four decimal places. Assume oxygen to be a perfect gas and take the specific heat at constant pressure as = 0 . 9 1 7 k J / k g K and molar gas constant as = 8,314 J / kmol K

A fluid enters a machine at 170 m/s, 800 kPa, and with a specific volume of 0.3 m^3/kg. The radiation heat loss is 25 kJ/kg. The internal energy decreases by 495 kJ/kg. If the fluid leaves at 330 m/s, 138 kPa, and 0.95 m^3/kg, determine the work done by the fulid in kJ/kg.
As shown on the right, a vertical piston–cylinder assembly containing a gas is placed on a hot plate. The piston initially rests on the stops. With the onset of heating, the gas pressure increases. At what pressure, in bar, does the piston start rising? The piston moves smoothly in the cylinder and g = 9.81 m/s2.
