The third laboratory work in the 8th-grade physics curriculum (specifically the widely used program) is titled "Measuring the Specific Heat Capacity of a Substance" ( 1.2.1 ). Another common variation for this grade level is "Determining Relative Air Humidity" ( 1.2.2 ).
Below is a detailed guide for the most common version: . Objective
and identified the material of the body based on your experimental data.
