(c) The temperature of the gas increases. (d) The internal energy of the gas remains constant.

The room temperature is 27 °C.To reduce heat flux, the skin is wrapped with a clothing material. What should be the thickness of the clothing material covering the surface of this skin tissue to reduce the heat flux to half of its original value? What is the temperature at the skin-clothing material interface? Note: if you think you need to have more information to solve this problem, you can make assumptions. Please state them clearly in your answer, if you need to make such assumptions.And please explain step by step to the answer to better understandingarrow_forwardA worker drives a 0.500 kg spike into a rail tie with a 2.50 kg sledgehammer.

- A small metal cube with a thermal mass mc and an initial temperature 0 is dropped into a container of water that is actively maintained at a constant temperature 0w. The cube quickly comes to rest on the bottom surface of the container. The bottom surface is maintained at a constant temperature 0 (note that this is different from 0w). The thermal resistance between the cube and the water is Rcw while the thermal resistance between the bottom surface of the container and the cube is RCB. The temperature of the cube is denoted by 0c. a) Draw the system schematic indicating the assumed directions of the heat transfer rates. Label all the nodes and system parameters. b) Derive the governing equation for the temperature of the cube, 0c. c) Where does to appear in the system schematic and how does it affect the governing equations? d) Calculate the steady-state temperature of the cube, css, assuming the following system parameters: 0o = 21°C, 0B = 6°C, 0w = 0°C, Rcw = 2°C/W, and RCB = 4°C/Warrow_forwardIn a Styrofoam cup containing 60.0 grams of water at 87.6°C, a 13.9 gram sample of an unknown metal is put at 27.5°C.The water cools down and the metal warms up until thermal equilibrium is achieved at 64.3°C. Determine the specific heat potential of the unknown metal by assuming that all of the heat lost by the water is gained by the metal and that the cup is completely insulated. The specific heat capacity of water is 4.18 J/g/°C.arrow_forwardThe rate at which a resting person converts food energy is called one’s basal metabolic rate (BMR). Assume that the resulting internal energy leaves a person’s body by radiation and convection of dry air. When you jog, most of the food energy you burn above your BMR becomes internalenergy that would raise your body temperature if it were not eliminated. Assume that evaporation of perspiration is the mechanism for eliminating this energy. Suppose a person is jogging for “maximum fat burning,” converting food energy at the rate 400 kcal/h above his BMR, and putting out energy by work at the rate 60.0 W. Assume that the heat of evaporation of water at body temperature is equal to its heat of vaporization at 100°C. (a) Determine the hourly rate at which water must evaporate from his skin. (b) When you metabolize fat, the hydrogen atoms in the fat molecule are transferred to oxygen to form water.

- Why does hot water with a layer of hot oil cool more slowly than water without oil? Select the correct explanation. Oil has a much lower specific heat capacity than water, and the water combined with the oil layer cools more slowly than the water without oil. The oil layer prevents the water from evaporating, which increases the rate of change of internal energy of the water. Oil has a much higher specific heat capacity than water, and the water combined with the oil layer cools more slowly than the water without oil. The oil layer prevents the water from evaporating, which decreases the rate of change of internal energy of the water.arrow_forwardAn electric generator at a power plant produces energy by passing superheated steam from a high temperature container (reservoir), through a pipe connected to a series of fans, and then into a low temperature reservoir. As the steam passes across the blades of the fans some of the heat energy of the steam is transformed into mechanical energy, which turns the fans which in turn are connected to a generator, which in turn converts the mechanical energy into electrical energy. If the high temperature steam has a temperature of 376 K and the low temperature reservoir has a temperature of 101.9 K, what is the Carnot efficiency of this process?arrow_forwardDuring a chemistry lab, you take a 0.4 kg sample of ice and put it in a beaker with a thermometer. You then place the beaker with the ice on 0 the temperature of the ice is -18 = a hot plate, and turn on the hot plate. This hot plate adds heat to the ice at a rate of 330 W. At time t °C. Because of the large heat capacity of water and ice, you may assume in this problem that all the heat goes into the sample of ice, and that we can ignore the amount of heat going into the beaker and thermometer. Also assume no heat escapes from the system.
