Q (heat) = mass*Specific Heat*Temperature differenceI assume 2.5 * 101 Joules? or 25 J & 10 grams of substance?25 J = 10 grams * (SH) * (70-10oC)25 J =10 g *60oC * SHSH = 25 J/(10 g * 60oC)S.H. = 0.0417 J/gOC
m stands for massE is energy, m is mass, and c is the speed of light.The formula shows what the energy equivalent of matter is: the energy obtained by changing a gram of mass to energy is 25 million kilowatt hours or 9 x 1013 joules.
