Estimate the final temperature and the work required when 1 mol of n-butane is compressed isentropically in a steady-flow process from 1 bar and 50°c to 7.8 bar. assume the following: • the process is reversible and adiabatic. • the work it asks for is the shaft work. • use the lee-kesler correlation. in this problem, keep the first two terms (a- and b-terms) of the ideal-gas-state heat capacity (table c.1) only in your calculation.

we need the questions , i may then you.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.
