Reference no: EM131635173

The sculptor has prepared a mold for casting a bronze figure. The figure has a volume of 225Ml. Bronze has a density of 10.5 g/ml. The melting point of bronze is about 950.0 degree Celsius and its heat capacity (specific heat) is .435 J/g degree Celsius.

(a) How many significant figures are in the melting point temperature of bronze?

(b) How many ounces of bronze are needed in the preparation of the bronze figure? (1 ounce =28.35g).

(c) What is the melting point of bronze in degree Fahrenheit and kelvin.

(d) If 659g of bronze was used to casting the bronze figure abd and bronze had specific gravity of 7.7, what volume of bronze was used in casting the mold for the figure?
