Describe methods of heat transfer. Give examples.
Solution
there are three methods of Heat transfer
1) conduction ex:if we put one end of metal rod into furnace at higher temperature and other end at room temp.
then after some time we found that temp of other end is also incresed this mode of heat transfer is known as conduction {generally happens in solids}
2)convection ex:if we take a metal body and we put it in steam flow then the temp of body increses .this mode of heat transfer is known as convection {generally happens in liquids and gases}
3)radiation ex:energy comming from sun in the form of rays is known as radiation.{no material medium is required}
