Macmillan Learning You happen to come across a piece of metal that has a density of p = 7.89 g/cm when the temperature is To = 55.0 C. If the metal is cooled to a temperature of T = 0.00 C, does the density change? Yes, the density will decrease since the volume changes. No, because as the volume changes so does the mass. O No, density does not depend on temperature. O Yes, since the metal contracts and the mass is constant, the density will increase. D Calculate the density of the piece of metal at this temperature, p. The coefficient of volume expansion for this piece of metal is B = 6.27 x 10-5 1/C. PL = g/cm
