Heat and Temperature

   this is the result of learning Heat and Matters. i hope it will be useful for us ^^

      What is temperature? temperature is the degree of hotness and coldness of something. with the other word, temperature is a common quantity that is had by a system.
      How to measure the temperature of a system? actually we can't measure the exactly temperature of a system. but, we can compare the internal energy of a system with the other system. usually, we use Thermometer to measure or to compare the temperature of a system. Measuring means Comparing. so, along this time we measure the temperature means we compare the internal energy of a system with the other system and it is scaled by the thermometer.
Thermometer usually made from glass, and it is colorless to make the temperature easy to observe (readable). the material inside the thermometer, usually is alcohol or mercury because just this two liquid that has linear movement. this two liquid have thermometric property. Thermometric property is a characteristic of an object which is change when the temperature is change. the number or scale that shown in measurement of the temperature of a system means the heat potentially owned by that system.
