An ablator is vaporized in the dynamic “ramp” form of this process, which provides gentler conditions for equation of state measurements. An interferometer called VISAR is used to measure velocity when performing this process on a solid using laser-induced shockwaves, which was used to create superionic ice (-5[1])in 2018. A thermodynamic quantity named for this process is the inverse of the bulk modulus. For a real gas, (15[1])this process names a (*) “factor” denoted Z that is equal to (10[1])pV over nRT. This process causes ignition in a diesel engine. The surroundings (-5[1])perform work on the system in the two steps of the Carnot cycle corresponding to this process, which follow two expansion steps. For 10 points, name this process in which the volume of a system decreases, often (10[1])via a piston. ■END■ (10[1])
