What is the temperature of fusion, Tfusion, and vaporization, Tvapor, for this unknown substance?

Y intercept is Temperature (C)

X intercept is Time

Start at (0,-60C)

then (20,80C) to (50,80C)

increase to (100,280C) to (140,280C)

increase to (160,360C)

For a sample of 67.4 g of this substance with a specific heat of 49.9 J/kg·C, how much heat is added to the substance if the temperature is to change from 180.0C to 250.0C?

Q= ? J
