Question

Please do not write the answers ONLY, but write the steps and laws with the answers.

Nickel at 1 atm:

Boiling point = 2732.0°C	Heat of vaporization = 1.542 x 10^3 cal/g
Melting point = 1453.0°C	Heat of fusion = 71.71 cal/g
Specific heat solid= 0.1061 cal/g°C
Specific heat liquid = 0.1750 cal/g°C

How many kcal of heat are needed to raise the temperature of the sample to 1691.0°C? If a 45.12 g sample of solid nickel is initially at 1334.0°C.

..........kcal

Answer 1

The biggest take away is to split the temperature change into 3 parts (Q1, Q2, and Q3) with Q2 referring to the phase change from solid to liquid (melting point, using heat of fusion) and then totaling them all up to get the total energy. Attached is a video for a full explanation walk-through. Hope this helps!
