In the classical model of a hydrogen atom, an electron orbits a proton with a kinetic energy of +13.6 ev and an electric potential energy of -27.2 ev hint (a) use the kinetic energy to calculate the classical orbital speed (in m/s). m/s (b) use the electric potential energy to calculate the classical orbital radius in m)

What belongs in the areas marked x and y? x: the internal energy of a piston system increases as heat is added and rises to a cool area y: as thermal energy is added to a container, some of the energy is lost to the environment x: as thermal energy is added to a container, some of the energy is lost to the environment y: the internal energy of a piston system increases as heat is added and rises to a cool area x: a cold spoon placed in hot liquid gets warmer y: thermal energy is converted to light energy x: thermal energy is converted to light energy y: a cold spoon placed in hot liquid gets warmer
