Hi i'm Cody and I go to lee centralmiddle school i'm in 6th grade, and i'm going to talk about heat transfer.
Heat is the kinetic energyfrom one medium or object to another, or for an energy source to a medium or object.
heat transfer is the movement of heat across the border of the system due to a difference in temperature between the system and its surroundings.
conduction is the transfer of energy as heat or electricity for some examples touching a hot stove or walking on hot sand.
Radiation includes emanation of any portion of the electromagnetic spectrum, plus it includes the release of particles. Examples include: A burning candle emits radiation in the form of heat and light. The Sun emits radiation in the form of light, heat, and particles.
radiator - A radiator puts warm air out at the top and draws in cooler air at the bottom. steaming cup of hot tea - The steam you see when drinking a cup of hot tea indicates that heat is being transferred into the air. ice melting - Ice melts because heat moves to the ice from the air.
