WebHeat is a phenomenon involving whole atoms. In solid metals the atoms are arranged in a regular structure. When the metal is heated, the atoms vibrate, influencing their neighbors to vibrate as well. Metals are malleable and ductile because sheets of these atoms can slip gradually past one another. Gibe. WebBut it is quite easy to do a separate experiment to determine the total heat capacity of the calorimeter. You often set up your calculations like this: heat for water + heat for object + heat for calorimeter = 0. q₁ + q₂ + q₃ = 0. q₁ = m₁s₁ΔT₁ for the water. q₂ = m₂s₂ΔT₂ for the object. q₃ = CΔT for the calorimeter.
