write an experiment to show that black surfaces absorb heat energy more than shiny polished surfaces or white surface​

One example of an experiment you can do is find out the heat difference between a white car and a black car using the sun in a hot day.

Explanation: The black car would absorb more heat from the sun and would make the inside of the black car hotter than the white car.

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.
