Gold has a density of 1.932 x 104 kg/m3 at 0C and an average linear expansion coefficient of 1.420 x 10-5(c-1). A 55.00 kg block of gold at 0C is heated to 70.00C. (a) What is the density (in kg/m) of the gold block at 70.00C? (Round your answer to at least four significant figures.) x You may have used the linear expansion coefficient value for the volume expansion coefficient. How are the two related for a solid? kg/m (b) What is the mass (in kg) of the gold block at 70.00C? X kg
