Specific Heat |
Def: the amount of heat it takes to raise the temperature of one gram of any substance by one °C.
Q = mc∆TQ = energy: J
m= mass: g c= specific heat: J/(g°C) ∆T= change in temperate (final-initial): °C |
Energy of Phase Change |
Def: Heat energy is gained/lost during a phase change. There is no change in temperature until the phase change is complete. On the graph below, you can see phase change during the plateau on the heating/cooling curve.
q= molΔH q = energy: J
mol= amount: mol ∆H= enthalpy, heat energy gained or lost per amount o substance: J/mol |
