A Wrong Idea
Often the concepts of heat and temperature are thought to be the same,but they are not.
Perhaps the reason the two are usually and incorrectly thought to be the same is because as human beings on Earth everyday experience leads us to notice that when you heat something up,say like putting a pot of water on the stove,then the temperature of that something goes up.More heat,more temperature - they must be the same,right?Turns out,though,this is not true.
--------------------------------------------------------------------------------
Initial Definitions
Temperature is a number that is related to the average kinetic energy of the molecules of a substance.If temperature is measured in Kelvin degrees,then this number is directly proportional to the average kinetic energy of the molecules.
Heat is a measurement of the total energy in a substance.That total energy is made up of not only of the kinetic energies of the molecules of the substance,but total energy is also made up of the potential energies of the molecules.
--------------------------------------------------------------------------------
More About Temperature
So,temperature is not energy.It is,though,a number that relates to one type of energy possessed by the molecules of a substance.Temperature directly relates to the kinetic energy of the molecules.The molecules have another type of energy besides kinetic,however; they have potential energy,also.Temperature readings do not tell you anything directly about this potential energy.
Temperature can be measured in a variety of units.If you measure it in degrees Kelvin,then the temperature value is directly proportional to the average kinetic energy of the molecules in the substance.Notice we did not say that temperature is the kinetic energy.We said it is a number,if in degrees Kelvin,is proportional to the average kinetic energies of the molecules; that is,if you double the Kelvin temperature of a substance,you double the average kinetic energy of its molecules.
--------------------------------------------------------------------------------
More About Heat
Heat is energy.
Heat is the total amount of energy possessed by the molecules in a piece of matter.This energy is both kinetic energy and potential energy.
When heat,(i.e.,energy),goes into a substance one of two things can happen:
1.The substance can experience a raise in temperature.That is,the heat can be used to speed up the molecules of the substance.Since Kelvin temperature is directly proportional to the average kinetic energy of molecules in a substance,an factor increase in temperature causes an equal factor increase in the average kinetic energy of the molecules.And if the kinetic energy of the molecules increase,the speed of the molecules will increase,although these increases are not directly proportional.The kinetic energy of a body is proportional to the square of the speed of the body.
2.The substance can change state.For example,if the substance is ice,it can melt into water.Perhaps surprisingly,this change does not cause a raise in temperature.The moment before melting the average kinetic energy of the ice molecules is the same as the average kinetic energy of the water molecules a moment after melting.Although heat is absorbed by this change of state,the absorbed energy is not used to speed up the molecules.The energy is used to change the bonding between the molecules.Changing the manner in which the molecules bond to one another constitutes a change in potential energy.Heat comes in and there is an increase in the potential energy of the molecules.Their kinetic energy remains unchanged.
So,when heat comes into a substance,energy comes into a substance.That energy can be used to increase the kinetic energy of the molecules,which would cause an increase in temperature.Or that heat could be used to increase the potential energy of the molecules causing a change in state that is not accompanied by an increase in temperature.

III.Hundreds of years ago,life was much harder than it is today.People didn't have modern machines.Life today has new problems.One of the biggest is pollution.Water pollution has made our rivers and lakes dirty.It kills fish and makes our drinking water dirty.Noise pollution makes us talk louder and get angry much easier.Air pollution is the most serious kind of pollution.Cars,planes,motorbikes,buses and factories all pollute our air.Many countries are making new laws to fight pollution.We should put waste things in the dustbin and not throw them on the ground.We can go to work by bus.If there are fewer people driving,there will be less pollution.

Let's be friends of the earth
People have lived on the earth for millions of years.Many years ago,the earth was clean.Today,there is air pollution,water pollution and land pollution.Friends of the earth are the people who help to protect the environment.To be friends of the earth,we promise to make less rubbish and never pollute the earth.We also promise to plant more trees and flowers to make the earth more beautiful.By the way,we must use fewer plastic cups,knives and forks at the beaches.We also must pick up litter and put it into litter bins.We should do a lot to improve the environment.Let's be good friends of the earth.
