The following graph is the heating curve for a 1.25-kg sample of a substance.
The heating curve for a sample is shown with temperature on the y-axis from 0 to 350 degrees Celsius and heat added on the x axis from 0 to 1200 Joules. Five segments connect points from 0, 0 to 200, 50 to 400, 50 to 600, 200 to 1000, 200 to 1200, 300.
What is the specific heat of the solid phase?
