Heat transfer

convection, conduction, radiation


Radiation is the transfer of heat from one place to another using invisible waves all objects a give out heat via radiation but hot object radiate more heat than cool objects dark objects radiate more heat than light object

An example of an every day life radiation is the sun

heat can be transferred from one place to another by convection. in convection hotter particles rise and cooler particles fall and then it starts again and keeps going around

an example is when you boil water

heat can be transferred by conduction when an object is heated the particles in the object begin to vibrate these vibrations are passed through the object. transferring the heat from one end to the other

if you leave a car in the sun it will be hotter if it is in the sun
