(1) Determine the specific heat of the object; (2) Determine the electric heat equivalent.
When the specific heat of the object is measured, the cover can be tested by replacing the cover plug on the cover frame. If you want to exchange the experiment to determine the electric heating equivalent, then replace the assembly with the heating wire for use, which is convenient and practical when changing the experiment.
Technical requirements: 1. The heating wire is a nickel-chromium resistance wire with a resistance value of 2±0.1Q and 1±0.1Ω.
