The best way to measure the thermal energy of an object is to use a thermometer. A thermometer is a glass tube filled with a liquid (mercury) which expands or contracts depending on the temperature of the object it is in contact with. It measures the average kinetic energy (one type of thermal energy) of the molecules of a substance in degrees Fahrenheit (F) or Celsius (C). Not all the molecules have the same amount of kinetic energy because the molecules are traveling in random directions ...
The device used to measure changes in thermal energy is called a calorimeter. What is the temperature of a field? A measure of the average thermal energy of the molecules in it.
The calorimeter is used to measure the thermal power and its changes at different stages of the thermodynamic process, by means of a power meter or an oscilloscope-calorimeter. The design of the calorimetric system and the method of measurement distinguish between liquid and massive calorimeters, single and double (differential).
Electric resistance thermometer was developed after the liquid in glass type thermometer. In this, the change in the resistance of a metal wire due to change in the temperature is measured. When electric current flows through the wire then the wires scatter of each other due to the electric resistance.
Calorimetry is used to measure amounts of heat transferred to or from a substance. A calorimeter is a device used to measure the amount of heat involved in a chemical or physical process. This means that the amount of heat produced or consumed in the reaction equals the amount of heat absorbed or lost by the solution.
Thermal energy results in something having an internal temperature, and that temperature can be measured - for example, in degrees Celsius or Fahrenheit on a thermometer.
The measurement of mass change using temperature thermogravimetry (TG) was discovered by Honda, a physicist from Japan. The use of thermal analysis for kinetic purposes was invented by the Japanese electrical engineers, Kujirai and Akahira. During those days, automatic techniques for thermal analysis were still unknown.
