A house, for cooling purposes, consists of two zones: the attic area zone A and the living area zone B (see below figure). The living area is cooled by a 2-ton air conditioning unit that removes 31,000 Btu/hr. The 1 heat capacity of zone B is ,°F per thousand Btu. The time constant for 8 heat transfer between zone A and the outside is 4 hr, between zone B and the outside is 8 hr, and between the two zones is 8 hr. If the outside temperature stays at 90°F, how warm does it eventually get in the attic zone A? It eventually gets to be (Type an integer or decimal rounded to the nearest hundredth as needed °F in the attic zone A.

Q4/ How much heat is required to raise the temperature of 30 Kg air in the room from 5c'to 20c'when a heater is used to heat this room ,under this conditions the specific heat capacity of air=1000 J/Kg.K

Solve it quickly please

Thermodynamics: Can you show me how to solve for the answer that is written below? Please show it in step by step solution Thank you!

solve the (1st) question only

i want help with all these questions asap

6. a. The heat flux applied to the walls of the biomass combustion furnace is 20 W/m2. The furnace walls have a thickness of 10 mm and a thermal conductivity of 12 W/m.K. If the wall surface temperature is measured to be 50oC on the left and 30oC on the right, prove that conduction heat transfer occurs at a steady state!b. Heating the iron cylinder on the bottom side is done by placing the iron on the hotplate. This iron has a length of 20 cm. The surface temperature of the hotplate is set at 300oC while the top side of the iron is in contact with the still outside air. To reach the desired hotplate temperature, it takes 5 minutes. Then it takes 15 minutes to measure the temperature of the upper side of the iron cylinder at 300oC. Show 3 proofs that heat transfer occurs transiently

Give an example of application of the Oth law of thermodynamics in everyday life. List explicitly Systems 1, 2, and 3 and what is the purpose of them being at the same temperature.

A house, for cooling purposes, consists of two zones: the atric area zone A and the living area zone B (see below figure). The living area is cooled by a 2 -ton air conditioning unit that removes 23,000 Btu/hr. The heat capacity of zone B is 1/6 °F per thousand Btu. The time constant for heat transfer between zone A and the outside is 3ℎr, between zone B and the outside is 6ℎr, and between the two zones is 6ℎr. If the outside temperature stays at 90°F, how warm does it eventually get in the attic zone A ?

In an experiment to measure the specific heat of material, a student first measured the masses of the following samples as given in Table 1. Table 1: Measurement of Mass Physical quantity measured in (g) Value Mass of Styrofoam 2.4 cup Mass of Styrofoam 62 cup + water Mass of Brass sample 15.3 Mass of Copper sample 62.5 and then recorded the temperatures of the above two samples, in Table 2.
