According to the work-energy theorem, in the absence of friction, if you do 100J of work on a cart while pushing it across a horizontal surface, how much will you increase its kinetic energy?

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference

True or false when elements combine to form a mixture, the resulting chemical properties may be very different from those of the elements that make it.
