For the purposes of this problem, 10 kg of air in a 10-m3 rigid airtight tank are assumed to have only two independent properties, A and B. At time t1 = 0, measurements yield that A = 12 and B = 14, whereas at time t2 = 5 h the same measurements yield A = … Read more
Consider the descriptions given below in pairs, and indicate whit pairs specify the same system and whit the same state. Notice that the answers to this problem depend on how eat system is defined. For eat description, consider several alternative system definitions. (a) Two kilograms of water rotating at 1 rpm in a 2-liter liquid-proof … Read more

For the manufacturing of one day’s paper products a paper mill uses the necessary coal, oil, chemicals, and wood that are already stored in the mill. In addition, some of the energy needed in the mill is obtained from a waterfall of 10 6 kg of water per day falling over a difference in elevation … Read more
the sun emits energy continuously into the universe. the fraction of this energy flux intercepted by the earth is 1.75 x 1011 MW. the earth-sun distance is about 1.5 x 10 8 km, and the earth’s radius is about 6370 km. the radius of the sun is about 696,000 km and its density is about 1.4 … Read more
An isolated system A initially consists of a deuterium molecule, D2 , and an oxygen atom, O, confined within a fixed volume V. e constituents of A are in a ground-energy state. As a result of a spontaneous fusion reaction between the two D atoms, the constituents of A are transformed into a tritium atom, … Read more
