<u>Types Of Energy Transfers</u>
Heat can be transferred in three ways: by conduction, convection, and by radiation.
- Conduction is the transfer of energy from one molecule to another by direct contact.
- Convection is the movement of heat by a fluid such as water or air.
- Radiation is the transfer of heat by electromagnetic waves.
The ultimate fate of a star depends on its mass.
A massive star ends with a violent explosion called a supernova.
The matter ejected in a supernova explosion becomes a glowing supernova remnant.
Toward the end of its life, a massive supergiant star
has a central iron core, surrounded by a shell where
silicon is being fused to iron, surrounded by a shell
where oxygen is being fused, surrounded by a shell where
carbon is being fused, surrounded by a shell where helium is
being fused, surrounded by a shell where hydrogen is
being fused.
