OC. Energy has been removed as work done by the gas.
OD. Energy has been added as work done by the gas.

Why do scientists believe that light is made of streams of particles? scientists believe that light is made of streams of particles because only the presence of photons can explain phenomena observed during experiments on the photoelectric effect. these observations include only some frequencies of light causing the ejection of electrons, no time gap existing between light striking a metal and electrons being ejected, and intensity having no effect on the kinetic energy of the ejected electrons.

The slope of a velocity time graph over any interval of time gives the during that interval
