Tashia & Tobi Lab Report experiemt 5 INTRODUCTION In this experiment we were wanting to find the specific heat of an unknown metal and determining what metal it was by using the formula q=c X m X change of temperature. We did two trials to compare the two and see what we come up with. EXPERIMENTAL First we chose an unknown metal‚ in which our unknown was unknown metal 2‚ the metal was gray and irregular shaped. We setup the calorimeter and got a mass of it just being empty then we got
