one side of a copper sheet is highly polished and the other side is painted matt black. the copper sheet is very hot and placed in a verticle position. a student places her hands at equal distances from the sheet. explain why her hands are not heated by convection

Her hands are not heated by convection because radiation does not require material medium for its propagation.

 Radiation

Thus, student's hands were not heated by convection since convection is a mode where material medium is required for propagation of heat energy.

Because radiation does not require material medium for its propagation.

Explanation:

Radiation is one of the types of modes of heat transfer that takes place majorly in gases. Heat energy can be transferred through gases by radiation without heating up the intervening medium. Even, if the available molecules of gases are evacuated, the heat energy would propagate.

Thus, student's hands were not heated by convection since convection is a mode where material medium is required for propagation of heat energy.
