The left side of this equation tells how much energy Q the cylinder gives to the water while it cools. The right side of this equation tells how much energy Q the water and aluminum cup absorb from the cylinder to warm up. Because it is the same energy, they are equal. What is known in this equation? Mcyl 411.7 g, malum 46.5 g, malum+water = 175 g Can you find: mwater =? g Twater = Talum = 20°C (water and cup of room temperature) 90°C, T; = 35°C (hot cylinder and cool "cylinder+cup+water" temperatures) Tcyl kCal Calum = 0.22, Cwater 1 (specific heat of water and aluminum, measured in units kg-°C What are we looking for is Ccul - How we find it? Plug all the numbers into the equation (1), Ccul will be one unknown which you can calculate from the equation. Important, convert all the masses from grams to kilograms! After you find Ccyl, compare it to known value for the copper 0.093(our cylinder is made out of copper). |Ceyl -0.093| % : · 100% 0.093
I just have one question to clarify. The given problem stated that in the part of value of Eal=10×10(race to -6) psi and the given we have in the problem for the value of Est=10×10(race to -6). Why is that on the solving part in yoir solution you are using 10×10(race to 6) instead of 10×10(race to -6)? I'm just curious, how did it happen? Did the value will still be the same? Can you give me the reason? Thank you!

An air conditioner supplies cold air at the same temperature to each room on the fourth floor of the building shownin Fig. The floor plan is shown in Fig. The cold air flow produces an equal amount of heat flow ݍ out of each room. Write a set ofdifferential equations governing the temperature in each room, where To= temperature outside the building, Ro= resistance to heatflow through the outer walls, Ri= resistance to heat flow through the inner walls. Thermal capacitance of each room is C. Assumethat (1) all rooms are perfect squares, (2) there is no heat flow through the floors or ceilings, and (3) the temperature in each roomis uniform throughout the room. Take advantage of symmetry to reduce the number of differential equations to three.
