Line l had the equation y=-2x -1 . write the equation of the image of l after a dilation with a scale factor of 2, centered at the origin. write your answer in slope intercept form

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?

Carbon dioxide gas expands isotherm a turbine from 1 mpa, 500 k at 200 kpa. assuming the ideal gas model and neglecting the kinetic and potential energies, determine the change in entropy, heat transfer and work for each kilogram of co2.

What is the heat treatment of metals? what is the benefit of it? why and how it's useful? answer in details, do not write by hand.
