1. Second law of thermodynamics:
❖ What is the second law of thermodynamics? Well, this law talks about the quality of energy, while the quantity of energy and matter stays constant. This law tells us that heat will flow from a hotter object to a colder object, due to Newton’s second law and that when energy is transferring and transforming, some of the useful energy might be lost .
❖ Cyclic process of energy transfer is a when a series of process that remain the same state both when it leaves the system and when it started. For cyclic process of energy transfer, the total amount of the initial internal energy of the system is equal to the final internal energy of the system, which …show more content…
The total energy input / the density of coal = total kg consumed each day
2.16*10 14J/ 32.5*10 6 J/kg= total kg consumed each day 1 MJ= 1*10 6J
Total kg consumed each day= 6.65* 10 6kg
D.
1 tonne= 1000kg
We have a total of 6.65*10 6kg consumed each day
6.65*10 6kg /1000 kg = 6650 tonne
Since each rail truck contains 100 tonnes
6650 tonnes/ 100 tonnes = 66.5 rail trucks
We can’t have 0.5 of a rail truck, so we round up to 67 truck loads
