Best ResponseYou've already chosen the best response.2you need to use 2 equations, in 5 steps. (1) \(q=H_{fusion/vap}*m\) (2) \(q=m*C_p*\Delta T\) dw:1382470856637:dw In A, your heating up the ice from 24 to 0 degrees: use equation (2) and the appropriate \(C_P\). In B, the ice is melting, use equation (1), use appropriate \(H_{fusion}\) In C, you're heating up the water form 0 to 100 degrees, use equation (2). Use appropriate \(C_p\). In D, you're vaporizing/boiling the water, use equation (1), use appropriate \(H_{vap}\). In E, you're heating up the water vapour/steam, use equation (2), use appropriate \(C_p\).
