[QUOTE="Alice7979, post: 6020133, member: 647874"] [h2]Homework Statement [/h2] How much heat in joules must be added to 0.841 kg of aluminum to change it from a solid at 130 °C to a liquid at 660 °C (its melting point)? The latent heat of fusion for aluminum is 4.0 x 105 J/kg. [h2]Homework Equations[/h2] Q = mL Total = mc∆t + mL = m(c∆t +l) [h2]The Attempt at a Solution[/h2] i think it is it .841(.9(660-130) + 4*105) but the answer i get isn't right [/QUOTE]
