Instrumentation and Properties of Materials

Finally, the relationship between heat and temperature follows an Ohm s law form2  

2This equation is valid for steady-state one-dimensional conductive heat flow. 

3The lower temperature cones tend to have a high percentage of glassy phase of rapidly decreasing viscosity with increasing temperature. 

Although there axe a myriad of devices used to measure the temperature of an object, thermal analysis instruments predominantly use thermocouples, platinum resistance thermometers, and thermistors. Thus, only these items, with special emphasis on thermocouples, will be discussed.
