Which is a better conductor of thermal energy a plastic foam cup or window glass?

Window glass is a much better conductor of thermal energy than a plastic foam (styrofoam) cup. The exact "thermal conductivity" rating of window glass depends on its mineral composition . The thermal conductivity of styrofoam is very low, because it traps air in small pockets, and air has a very low thermal conductivity. That is why styrofoam is widely used as insulation.

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.
