C in thermochemistry
Weband C is called heat capacity. Heat capacity tells how much energy required by a substance to raise its temperature by 1°C. It has a unit of J/°C. We can make heat capacity dependent on mass, it means that, q = m csp ΔT … WebThermochemistry is the study of how much energy is absorbed or produced by a chemical reaction. This experiment will focus on a few concepts in thermochemistry. An important property of a substance is its specific heat. This measures how much energy (q) is required to affect a change in temperature ( T) of 1 oC per gram of substance. The
