Which is true energy cant be created but can disappear into nowhere or energy is able to be transferred from one into another or all moving objects including atoms have potential energy or an arrow stretched back on a bow is an example of 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
