The importance of the heat ( thermal energy )
The heat is a form of energy that transfers from the higher temperature object to the lower temperature object , and it transferred through the conduction , the convection and the radiation .
The heat is a thermal energy that flows from the warmer areas to the cooler areas , and the thermal energy is the total of all kinetic energies within a given system .
The temperature is the degree of hotness or coldness of a body , It is measured by three scales of measurement which are Fahrenheit , Celsius and Kelvin and it is the average kinetic energy within a given object .
The thermal energy is a part of the total energy of any object , Its measuring unit is the joule , and it is related to the temperature of an object , The heat energy can be transferred by three ways which are the convection , the conduction , and the radiation .
The heat and the temperature are not the same thing because the temperature is related to how hot or cold something is , The measuring devices of the temperature are the thermometers .
The importance of the heat
The heat is very important in our daily life in warming the house , cooking , heating the water and drying the washed clothes .
The heat has many usages in the industry as making and processing the food and manufacture of the glass , the paper , the textile , ………etc .
The steam has a high specific heat ( more than the water) , It is used to carry a lot of heat energy at high pressures to run the rail engines or the rotors in AC generators .
The water in the swimming pool remains cool even in summer and the people enjoy a lot staying inside the pool , Because the water has high specific heat .
We use the heat in cooking , We use the utensils for making tea or coffee , or cooking vegetables or rice .
The heat is used as a simple yet effective way to manage the pain and the joint or muscular stiffness , The deep and penetrating heat does not only relieve the pain but also it enhances the recovery process .
