A cell phone charger uses 4.83J (work input) when plugged into an outlet, but only 1.31 J (work output) actually goes into the cell phone battery. The remaining joules are lost as heat. That is why the battery feels warm after charging for a while. How efficient is the charger?

The diagrams to the right show the distribution and arrangement of gas particles in two different containers. according to kinetic-molecular theory, which of the following statements is true? check all that apply. if the temperatures of both containers are equal, container a has greater pressure than container b. if the volume of container a decreased, its pressure would decrease. if the pressure in both containers is equal, container a has a lower temperature than container b.
