Why can a substance's specific heat capacity change as the substance changes temperature? (For instance, consider water?)

It does not change.


You may be thinking about a phase change, during which the temperature of the substance does not change while heat is being adsorbed or released.

  • Heat capacity is the amount of heat needed to change a substances’ temperature by #1^o#C or #1^o#K. Specific heat is the heat needed to change 1g of substances’ temperature by #1^o#C or #1^o#K.
  • Heat capacity is dependent on the amount of substance, but specific heat capacity is independent of it.


Neither changes with a change in temperature.
