- vibration being a measure of the temperature. e may regard 
the sum of he molecular forces as the specific heat of the 
body, and the product of the sum of all the molecular forces by 
e mean amplitude of the oscillations, i.e. t oduct of the 
specific heat and the temperature, will be the quantity of heat or
