Question

How much heat is required to heat 19 g of solid silver from 100 ◦C to liquid silver at 961◦C? The specific heat of solid silver is 0.235 J/g ·◦ C, and the heat of fusion of silver at its melting point of 961◦C is 11.3 kJ/g.
Answer in units of kJ

DrBob222 · Answer

q1 = heat to raise T from 19 C to 961 C. q1 = mass Ag x specific heat Ag x (Tfinal-Tnitial) q2 = heat to melt Ag. q2 = mass Ag x heat fusion Total q = q1 + q2
