- On a certain day, the temperature dropped from 480F to 170F in 6 hours. What is the temperature change in 0C and in K? a) ∆TC = 17.220C, ∆TK = 17.22K. b) ∆TC = 310C, ∆TK = 31K. c) None of these.How much heat does it take to vaporize 800 g of liquid nitrogen (N 2)?Why do fishermen sail out to the sea in the night? What process helps them to sail easily to the sea in the night and come back to the shore in the morning? think about processes like conduction, convection and radiation
- What is the net heat current in radiation of an Ice cube at 0 °C if the surrounding air is at 20°C? The ice cube has sides of length 2.50 cm, the emissivity of ice is 0.96 and the Stefan-Boltzmann constant is o = 5.67 x 10-8 Watts/m2Kª. Is the heat flow out or into the ice cube, explain?Several containers filled with the same kind of ideal gas with the following masses and temperatures. Which box has the gas with the largest thermal energy? Box A 60 g -30°C O Box A Box D Box C O Box B Box B 50 g 0°C Box C 45 g 60°℃ Box D 35 g 100°CYou have a 5.3 inch diameter sphere heated to 335.0°F, which is inside of a large room with a surrounding temperature of Tsurr = 71.0°F. Treating the sphere as a blackbody, calculate the net heat transfer rate due to radiation between the sphere and its surrounds, in units of BTU/hr. The Stephan-Boltzmann Constant in English units is: σ = 1.714*10-9 BTU/(hr-ft2-°R4).
- Select all the correctly defined terms. (Hint: do not select the ones that are incorrectly defined) Law of conservation of energy presumes the total energy content of the universe is constant. Kinetic energy is attributed to the motion of the obicet and depends on the mass of the object and its velocity. O Potential cnergy is the energy associated with position or composition. Heat involves the transfer of energy between two objects due to a temperature difference. Work is a force acting over a distance Could also be transfer of cnergy from onc form to anotherSaturn's moon Titan has a mass of 1.3452 x 1023 kg , a diameter of 5,150 km, and an atmosphere made mostly of N2 at a constant temperature of -179 degrees Celsius. Assume that the pressure at the surface is 50% more than on Earth. What is your best estimate of Titan's atmosphere's R constant?
