Unformatted text preview: On the Celsius temperature scale, there are 100 equal divisions between the ice point (0 °C) and the steam point (100 °C). On the Fahrenheit temperature scale, there are 180 equal divisions between the ice point (32 °F) and the steam point (212 °F). For most scientific work , the Kelvin temperature scale is the scale of choice. One kelvin is equal in size to one Celsius degree; however, the temperature T on the Kelvin scale differs from the temperature T c on the Celsius scale by an additive constant of 273.15: T = T c + 273.15. The lower limit of temperature is called absolute zero and is designated as 0 K on the Kelvin scale. The operation of any thermometer is based on the change in some physical property with temperature; this physical property is called a thermometric property. Most substances expand when heated. For linear expansion, an object of length L 0 experiences a change in length ∆ L when the temperature changes by ∆ T : ∆ L = α L ∆ T , where α is the coefficient of linear expansion.coefficient of linear expansion....
