- #12. (14) A hot metal block in the shape of a cube whose edge has length 12 cm is at temperature 600 K. At what net rate does it radiate heat when it is placed in air at temperature 300 K? Assume perfect emissivity.A meteor melts when it enters the Earth’s atmosphere. Assuming that the meteor is primarily made of iron and that its initial temperature was −125°C outside of Earth’s atmosphere, calculate the minimum speed it must have had before it entered Earth’s atmosphere. (The specific heat, the melting point, and the latent heat of fusion for iron are 450 J/kg.°C, 1808°C, and 2.89 x 10^5 J/kg , respectively.)On the moon the surface temperature ranges from 390 K during the day to 1.03 x 102 K at night. Convert these temperatures to the Celsius and Fahrenheit scales. (a) 390 K in degrees Celsius; (b) 390 K in degrees Fahrenheit; (c) 1.03 x 102 K in degrees Celsius; (d) 1.03 x 102 K in degrees Fahrenheit.
- The density of water that is at 0°C is very nearly 1000 kg/m³ (it is actually 999.84 kg/m³), whereas the density of ice that is at 0°C is 917 kg/m³. Calculate the pressure necessary to keep 4.6 m³ of water from expanding when it freezes, neglecting the effect such a large pressure would have on the freezing temperature. (This problem gives you only an indication of how large the forces associated with freezing water might be.) The bulk modulus of ice is 2.20 x 109 N/m². How is density related to the mass and volume of a substance? How is the change in volume due to expansion or contraction related to the thermal stress? N/m²A brass (a=19 x 10-6 °c- 1 ) ring of diameter 10.01 cm at 20.0°C is heated and slipped over an aluminum rod (a = 24 x 10-60c-1 ) of diameter 10.4 cm at 20.0°C. Assuming the average coefficients of linear expansion are constant, to what temperature (in c-1) must this combination be cooled to separate them?A small chunk of dry ice (solid carbon dioxide) at 195 K is added to a thermally insulatedcontainer filled with liquid nitrogen at its boiling point of 77 K. What happens in thecontainer?(A) The dry ice melts until thermal equilibrium is established.(B) Some of the liquid nitrogen boils and the dry ice gets colder.(C) Some of the liquid nitrogen freezes and the chunk of dry ice gets larger.(D) An equilibrium temperature is reached without any phase changes occurring.
- it is important not to undercook chicken, otherwise you might get very sick. The inside of the chicken has to be at a certain temperature (75 C or 165 F) to make sure it is safe. Why can’t you just wait until the outside of the chicken is at this temperature? Why isn’t the entire chicken at the same temperature while it is being cooked?Your car’s radiator is made of steel and is filled with coolant. You fill the radiator to the very top with coolant, then drive off without remembering to replace the cap. As the coolant and steel radiator heats up, will the level of coolant drop or rise and overflow? why? what is a radiator is and what purpose does it serves in a car?
