. Fire doors are kept closed during a fireto (Points: 4)
       prevent radiant energyproduced by the fire from escaping.
       prevent convectioncurrents from fanning the flames of the fire.
           decrease the spread of the fire becauseconduction of the heat through the door is slower than conductionof heat by convection through the air.
       deprive the fire ofoxygen.

Explanation / Answer

Electricity is a form of nuclear energy is true,that's what given by a nuclear power plant Solar cell produce electricity with out any mechanicaldevieces, in which chemical energy is converted into electricalenergy. Coal prevent convection currents fromfanning the flames of the fire.
           decrease the spread of the fire becauseconduction of the heat through the door is slower than conductionof heat by convection through the air.
