Trong một chu trình nhiệt động, 50 g khí CO2

thể tích ban đầu V1
= 20 lít được biến đổi đẳng
tích đến trạng thái 2, sau đó tiếp tục
được giãn nở đẳng
áp đến trạng thái 3 có V3
= 30 lít và cuối cùng về lại trạng thái ban đầu thông qua quá trình nén đoạn
nhiệt. Nếu
biết công thay đổi thể tích của quá trình 2- 3 là W2-3
= 1,2 kJ, hãy xác định:

a/
Các thông số trạng thái cơ bản (p, V, T) của CO2
tại 1, 2 và 3.

b/
Công thay đổi thể tích và nhiệt lượng trao đổi trong từng quá trình.

Your starship, the aimless wanderer, lands on the mysterious planet mongo. as chief scientist-engineer, you make the following measurements: a 2.50-kg stone thrown upward from the ground at 14.0 m/s returns to the ground in 5.70 s ; the circumference of mongo at the equator is 2.20×10^5 km ; and there is no appreciable atmosphere on mongo. (a) the starship commander, captain confusion, asks for the following information: what is the mass of mongo? (b) if the aimless wanderer goes into a circular orbit 2.20×10^4 km above the surface of mongo, how many hours will it take the ship to complete one orbit? (c) an unmanned spacecraft is in a circular orbit around the moon, observing the lunar surface from an altitude of 44.0 km . to the dismay of scientists on earth, an electrical fault causes an on-board thruster to fire, decreasing the speed of the spacecraft by 23.0 m/s . if nothing is done to correct its orbit, with what speed (in km/h) will the spacecraft crash into the lunar surface?

Acommercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at -35°c by rejecting waste heat to cooling water that enters the condenser at 18°c at a rate of 0.25 kg/s and leaves at 26°c. the refrigerant enters the condenser at 1.2 mpa and 50°c. if the compressor consumes 3.3 kw of power, determine (a) the mass flow rate of the refrigerant, (b) the refrigeration load, (c) the cop, and (d) the minimum power input to the compressor for the same refrigeration load.
