A laboratory thermometer A is kept 7 cm away on the side of
the flame while a similar thermometer B is kept 7 cm above the
flame of a candle as shown in Figure
Which of the thermometers, A or B, will show a greater rise in
temperature? Give reason for your answer

The polised surface of tiles acts as good conductor of heat and the
wood acts as insulstor or bad conductor of heat , hence the basic
cause behind the heating effect can be tiles are good conductors of
heat , this can seen at night when tiles get cooled that that of
wood when no light falls its gets cooled hence reason a is
correct
In second question the heting due to radiation is greater than heat
due to convection henc ethe thermometre which is above the flame
measures greater temperature than side one
