Problem

Substance A has the following properties.

mp at 1 atm: −20.˚C               bp at 1 atm: 85°C

ΔHfus: 180. J/g                       ΔH   vap: 500. J/g

csolid: 1.0 J/g•°C                    c   liquid: 2.5 J/g•°C

cgas: 0.5 J/g•°C

At 1 atm, a 25-g sample of A is heated from −40.°∆C to 100.°C at a constant rate of 450. J/min. Perform any other necessary calculations, and draw a curve of temperature vs. time for the entire heating process.
