Please, I need help with this badly: Substance A has a normal melting point of -25.0 °C, an enthalpy of fusion of 1200 J g'; specific
heat for the solid is 3.00 Jg'c and the liquid is 6.20 J g''C'' Determine the heat needed to
change 150 grams of A from a solid at - 40.0 °C to a liquid at +70.0°c. Draw the diagram to
illustrate the process that is occurring.

the product of the pressure and volume is also constant
