The figure below is a heat curve for an unknown outerspace, Ask an Expert

Academics

The figure below is a heat curve for an unknown outerspace substance discovered by the Mars rover. By understanding the heat curve, scientists can make inferences about the composition of the planet. What is the temperature of fusion, Tfusion, and vaporization, Tvapor, for this unknown substance? Note that the units are graded. For a sample of 75.4 g of this substance with a specific heat of 54.8 J/kg·°C, how much heat is added to the substance if the temperature is to change from 180.0°C to 232.0°C?
