Calculate the time taken by the oil to cool from 500C to 400C given the surrounding temperature Ts = 250C.An unknown material with a mass of 1 kg is heated from 600C to 1000C. The amount of heat energy required was 15.2 kJ. Calculate the specific heat and identify the material.#19.13 FIND THE GIVEN, REQUIRED, SOLUTION AND EXPLAIN PER STEPS
- It takes 93.4 J of energy to heat a certain mass of a sample of lead from 22.3°C to 40.4°C. Find the mass of the lead. (Use-Specific heat of lead 0.129 J/g-K)You 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).(6) An aluminum tube is 30000m long at 200C. What is its length at (a) 1000C and (b) OoC?
