Answer to Question #38364 in Physical Chemistry for annie
2) A 1.0lb of gold ingot must be heated from 29c to its melting point. Calculate the energy required.
Mass of Pb:
m = 2*10^3 Kg,
Temperature difference Δ T = 600,61К - 298К = 302,61К
Specific Heat of Pb = 0.13 кJ/kg*K
2) The melting point of Au is 1337.33 K.
1 lb = 453.6 g
Mass of Au m = 0.4536 kg,
Temperature difference Δ T = 1337.33 К - (29+273) = 1035.33 К
Specific Heat of Au = 0.129 кJ/kg*K
