Question

The specific heat capacity of silver is 0.235 J/g ∙ K. Its melting point is 962 °C, and its enthalpy of fusion is 11.3 kJ/mol. What quantity of energy, in joules, is required to change 9.70 g of silver from a solid at 25 °C to a liquid at 962 °C?

Answer 1

To go from 25 to 962 degrees is a change of 937 degrees

q = (9.70 g)(0.235 J/g^o)(937^o) = 2136 J

q = (9.70 g)(11300 J/108g) = 1015 J

add them to get the total joules.
