Some electric hotplates are made of metal and they do not glow when they are hot. Other hotplates are made of glass and have a heater below them that glows red. The heater heats the glass. For both hotplates, there is no air gap between the hotplate and a metal pan that is placed on it. Which statement is correct?
- AThe glass hotplate transfers less energy by radiation to the base of the pan than the metal hotplate.
- BThe glass hotplate transfers energy by convection to the base of the pan.
- CThe metal hotplate transfers energy by conduction to the base of the pan.
- DThe metal hotplate transfers energy by convection to the base of the pan.
