The time now is 12.53am. I am still studying my chem and physic. I want to do well for my science!!
inter-molecular force
molecular vibration ( the particles vibrate and transferred the energy from the hot region to the cold region)
free electrons (Metal have the free electrons move rapidly and collide with one another and thus tranfer the energy even faster than liquid or gases)
convection current is set up whenever there is a movement in water/gases in particles. Because the volume will be increase, hot particle will be less dense and rise while the unheated will denser therefore sink which form a cycle.
Radiation is the process of transmission of thermal energy in the form electromagnetic waves.
infra-red radiation
good absorber is also a good emitter :)
tired already.. Bye
