Entropy is often called “time’s arrow” because it tells usin which direction natural processes occur. If a moviewere run backward, name some processes that you mightsee that would tell you that time was “running backward
The temperature in the deep interiors of some giant molecular clouds in the Milky Way galaxy is 50 K. Compare the amount of energy that would have to be transferred to this environment to the amount that would have to be transferred to a room temperature environment to bring about a 7.7 J/K increase in the entropy of the universe in each case. ΔEroom temp/ ΔEMilky Way =
It can be said that entropy is the greatness that provides us with information on the possibility of occurrence of a particular process and the quantification of it, whether or not a transformation can occur and what direction it occurs in. Time goes in a one-way direction, and as a result,some events have order to happen, for example, it is impossible to recover the heat dissipated to the environment as in the case of steam generators, some phenomena oneway.Which of the statements below represents an appropriate sentence for the concept of Entropy.(alternative 1:) time always runs from the past to the future;(alternative 2:) Physical reality always seeks a state of greater energy;(alternative 3:) the system naturally changes from a more orderly state to a more disordered one, from the least likely to the most likely;(alternative 4:) the system naturally changes from a more disordered state to a more orderly one, from the least likely to the most likely;(alternative 5:) None of the…
