Temperature (T):- Temperature is the measure of hotness or coldness of the substance expressed in terms of any several scales. :- It is fundamental physical quality. :- It is scalar quality. :- S.I unit of temperature is degree Celsius(°C) or Kelvin (k) . ***GENERALLY THREE TYPES SCALES ARE USED TO MEASURE THE TEMPERATURE. (1) Celsius Scale (2) Kelvin Scale (3) Fehrenheit scale ** Water is considered as the reference material for measuring temperature with scale. in which consider that freezing point of water in degree Celsius Scale is 0°C , Fahrenheit scale is 32°F and in Kelvin Scale is 273.15K and boiling point of water in degree Celsius Scale is 100°C , In Fahrenheit scale is 212°F and in Kelvin Scale is 373.15K. ### CONVERSION OF READING FROM ONE SCALE TO ANOTHER SCALE. ...
If a matter is heated(Temperature increase), the energy of the atoms present in it increases as well as the average distance between two atoms increases.The result due to which matter expands is called thermal expansion. ***There are three types of thermal expansion for solid. (1) Linear thermal expansion (2) Superficial thermal expansion (3) Volume thermal expansion. In this expansion matter expand without change in its states. (1) Linear thermal expansion Question (1). The length of a iron rod is 100cm at 15°C. When its temperature is raised to 115°C , then its length becomes 100.25cm . Calculate he coefficient of linear thermal expansion. (2) Calculate the change in length of steel rod of leng...
