What is Conduction?
Conduction is the way that it does not transfer heat through direct contact
Conduction is the process of heat transfer through fluids, liquids, or gases
Conduction is when you heat a pot of water on the stove
Conduction is the transfer of energy, such as heat or an electric charge, through a substance
What is Convection?
Convection is the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise
Convection is when you have hot air circulating through a fan
Convection is a solid form and tightly packed together
Convection is when molecules are combined together and not moving around freely
What is Radiation
Radiation is a isotope and can be used as a glass full of heavy water at room temperature
Radiation is when heat transfers over and creates a wave
Radiation is the emission or transmission of energy in the form of waves or particles through space or a material medium
Radiation is when EM waves take over and creates a chemical form
