• 14:09, 14 April 2022 Physdemo talk contribs created page Mechanical Equiv. of Heat (Created page with "{{NewDemo|subject=Thermodynamics|topic=Heat and the First Law|file1=Mechanical_equiv_of_Heat.gif}} A copper calorimeter is attatched to a crank. A rope is wrapped around the calorimeter and attatched to a 1 kg. mass. When the crank is turned the mass is raised a few centimeters off the floor and held there by the frictional force between the rope and calorimeter. The mechanical equivalent of heat can be calculated by determining the frictional work done by the calorimet...")
