Enthalpy of combustion (∆Hc) - ANSWER-The enthalpy change that occurs when one mole of a substance is burnt completely in oxygen under standard conditions Enthalpy of Formation (∆Hf) - ANSWER-The enthalpy change that occurs when one mole of a substance is formed from its elements in their standard states under standard conditions Enthalpy - ANSWER-The thermal energy stored in a chemical system. It is defined by: Enthalpy = Internal energy of the system + (pressure x volume) H = U...

temperature is related to KE how? temp is the average kinetic energy thermal energy is related to KE how? thermal energy is the total KE Brainpower enthalpy of fusion is ALWAYS greater than enthalpy of vaporization because? it has to break more bonds (solid --> liquid) the amount of heat depends on (2 factors) 1. the type of substance 2. the amount of the substance during a phase change does temperature change? NO if an archaebacerial species lives in a pool that is 0.01 M HCL wh...
