A study is done on the population of a certain fish species in a lake. Suppose that the population size P(t) after t years is given by the following exponentia function
P(1) - 510(0.72)

Find the initial population size.

Does the function represent
growth or decay?

By what percent does the population size change each year?

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.
