Document Summary
Guidance: please answer each question to the best of your ability. Make sure your response is legible, precise, includes relevant dimensional units (where appropriate), logically presented (include non-mathematical language in addition to mathematical language if necessary to convey your intent clearly and transparently), and state all assumptions you invoke. You are free to use your equations handbook, calculator, and writing instrument of your choice. If you have any doubt(s) about the meaning/intent of a question(s), please ask immediately so you do not wander off on an incorrect path. Please do not ask your colleague to borrow their handbook or calculator or writing instrument. Since enthalpy is a state function, it can be written as a function of the state variables temperature (t) and pressure (p), h(p,t). Thus, the total differential of enthalpy of a substance (solid, liquid, gas) can be expressed as: dh (p, t ) = The constant pressure heat capacity of a substance is defined as c.
