On a cold day, you grab a piece of metal and a fallen tree limb, both with bare hands. Both have been lying outside for a long time and are at the same temperature. The metal feels colder than the tree limb. Why?
In the morning of a hot day, you and your friends decide to have a picnic. You buy some drinks and load them, with ice, in a cooler. In order to keep the drinks as cold as possible, one of your friends decides to cover the cooler with a wool blanket. Would this actually keep the drinks cold or it just going to warm them?
A 6.25 kg block ice at 0 degrees Celsius is being warmed on a glass stove top. The thermal conductivity of the glass is 1.00 W/ (m K) and the glass is 0.50 cm thick. If the radiator plate underneath the glass raises the temperature of the bottom of the glass to 125 degrees Celsius, how long would it take to completely melt the ice? Assume the ice remains a solid rectangle with a square base of side 15 cm as it melts.
B. What is the rate of entropy change in Joules/ Kelvin/ seconds of the melting ice?

- A styrofoam cooler (k = 0.030 W/(m-°C) has outside dimensions of 0.170 m x 0.250 m x 0.260 m, and an average thickness of 2.0 cm. How long will it take for 1.10 kg of ice at -5.0°C to melt (to water at 0°C) in the cooler if the outside temperature is 34.0°C? Assume that ice temperature increases linearly from -5.0°C to 0°C. Neglect any temperature change of the air in the cooler. Data: Specific heat of ice is 2050 J/(kg-K). Laten heat of fusion of water is 3.34×105 J/kg.arrow_forwardA computer chip inside an orbiting satellite heats up during operation. Since there is no air in the satellite the only cooling will be by radiation. The chip is 1.50 cm wide by 2.50 cm long with a negligible thickness, and assume that the chip radiates heat evenly from both the top and bottom surfaces. The chip has an emissivity of 0.600 and dissipates 0.410 Watts during usage. Assuming that the inside temperature of the satellite is held at a constant -100.0°C; calculate the surface temperature of the chip in units of Celsius.arrow_forwardA pure aluminum plate is part of a heat shield for a manufacturing process. The aluminum plate has a thickness of 3.60 mm. The aluminum plate is insulated (on one side only) with Board and Slab insulation (Cellular glass, density of 145 kg/m3) 6.00 cm thick; which in turn is covered with a layer of Particle board (high density) 1.00 cm thick (The composite wall goes: aluminum/cellular glass insulation/Particle board). The temperature on the exposed surface of the aluminum plate is measured to be 78.0°C, while the outside surface of the Particle board is exposed to convection, T = 22.0°C, h = 17.0 W/(m2-K). The plate has dimensions of 11.50 m long by 3.50 m tall. • Draw and label a sketch of this system. Includedimensions, known temperatures, etc. • Draw and completely label the corresponding 1-Dsteady-state conduction resistor diagram. • Determine the heat transfer rate through thiscomposite plate. • Calculate the temperature at the Cellular Glassinsulation/Particle board interface.arrow_forward
- Consider a person standing in a room at 20°C with an exposed surface area of 1.7 m2. The deep body temperature of the human body is 37°C, and the thermal conductivity of the human tissue near the skin is about 0.3 W/m K. The body is losing heat at a rate of 150 W by natural convection and radiation to the surroundings. Taking the body temperature 0,5 cm beneath the skin to be 37°C, determine the skin temperature of the person.arrow_forwardThe coefficient of linear expansion of aluminum is 24 × 10-6 K-1 and the coefficient of volume expansion of olive oil is 0.68 × 10-3 K-1. A novice cook, in preparation for deep-frying some potatoes, fills a 1.00-L aluminum pot to the brim and heats the oil and the pot from an initial temperature of 15°C to 190°C. To his consternation some olive oil spills over the top. How much?arrow_forwardA child running a temperature of 101°F is given an antipyrin (i.e. a medicine that lowers fever) which causes an increase in the rate of evaporation of sweat from his body. If the fever is brought down to 98 °F in 20 minutes, what is the average rate of extra evaporation caused, by the drug. Assume the evaporation mechanism to be the only way by which heat is lost. The mass of the child is 30 kg. The specific heat of human body is approximately the same as that of water, and latent heat of evaporation of water at that temperature is about 580 cal g-1.arrow_forward

Initially, the temperature is 18.7 °C, and the beaker is filled to the brim. A short time later when the student returns, the temperature has risen to 95.5 °C. The coefficient of volume expansion of coffee is the same as that of water. How much coffee (in cubic meters) has spilled out of the beaker? Cold Hot Number i Unitsarrow_forwardA stone floor feels very cold to bare feet in the winter but a carpet in the same room feels comfortably warm. Why?arrow_forwardThe air temperature above coastal areas is profoundly influenced by the large specific heat of water. One reason is that the energy released when 1 cubic meter of water cools by 1.0°C will raise the temperature of an enormously larger volume of air by 1.0°C. Estimate that volume of air. The specific heat of air is approximately 1.0 kJ/kg ? °C. Take the density of air to be 1.3 kg/m3.arrow_forward
