Description
The Mechanical Equivalent of Heat (J apparatus) is a classic Griffin-style teaching unit used to show how mechanical work can be converted into heat, then compared with electrical heating. It is designed for practical lessons where energy input and temperature rise can be related using first principles.
The apparatus heats a solid copper calorimeter by two methods, mechanical friction heating and electrical heating, allowing direct comparison of the resulting temperature change. Temperature measurement is performed using a thermometer, supporting straightforward data collection for heat and energy calculations.
FAQs
Q: What does the J apparatus demonstrate?
