alloys specific heat - Alloys Specific Heat; alloys specific heat - The specific heat of alloys was found by Regnault to be very nearly the mean of the specific heats of the constituents. The following rule for obtaining the specific heat of alloys gives a very close approximation to the figures obtained by actual experiment: Multiply the specific heat of each constituent into the percentage amount of it contained in the alloy, and divide the sum of the products by 100. Alloys are not, as a rule, such good conductors of heat and electricity as the metals of which they are made.
