Methylene chloride has a melting point of - 94.8°C, a boiling point of 40.0°C, a specific heat of 1.21 J/g *K for the solid and liquid, and 0.608 J/g*K for the gas. The heats of fusion and vaporization are ΔHfus of 73.40 J/g, and ΔHvap of 334.35 J/g respectively. Determine how many joules of energy are needed to heat 40 grams of methylene chloride from -171.4 ° F to 333 K. Draw out and label your heating curve. This will...

Research the melting point, boiling point, heat of fusion, heat of vaporization, and heat capacity values for ethanol. Use these values to sketch a heating curve for ethanol. The relative slopes of the rising portions and the lengths of the flat portions should correspond roughly with the values you researched. There is no need to mark any values on the x axis.
