The specific heat of an object is a measure of the amount of heat required to raise the temperature of the oject by one degree.However, for most materials, the specific heat varies as the temperature varies. For particular material specific heat and temperature are realated by c=6.5+(1*10^-2)T+(2*10^-4)T^2 TBU/lb °F. At what temp. does the specific heat for this material reach a minimum?
