We feel hot when we go near burning fire. We feel hot and when we dip our finger in the boliling water.But why is it so ? It is so because the matter conatins heat.Heat is a for of energy that gives us sensation of warmth.
Topics needed to be learnt in the Heat
1)Effects of Heat
2)Anamolous Expansion of water
3)Specific Heat Capacity
3) Heat Equation
4)Some reasoning questions and numerical problems.
Ok lets get started towards our Lesson.
We fell various uses of heat in our daily life. Get out of the room and you feel the heat emmited by the sun. The Sun is the main source of heat and energy for Earth.Heat is used in our daily life . For ex.It is used to cook food,dry up your hair etc.The transfer of heat can be in two ways:conduction and radiation. We dont have to focus on these topics in the eye of the examination.
Well temperature and heat are related topic and are similar but not the same.Heat is defined as the total kinetic energy possesed by a body whereas Temperature is the average kinetic energy possesed by a body. We can take an example of water and match-stick.A burning match stick has an average temprature of 200 C but a bucket of boiling water has only the temperature of 100C.In this sense temperature is more in the match stick as compared to the water but water has more heat because its mass is more than match stick. So, it can be cleared there is difference between temperature and Heat.
