SUMMARY

The discussion focuses on calculating the energy absorbed by water and the heat produced per gram of fuel burned. The key formula involves using the change in enthalpy (\Delta H) to determine the thermal energy released from fuel combustion, which is then divided by the mole amount of the compound to find the molar enthalpy. Additionally, the heat absorbance capacity of water can be determined using a phase diagram, which provides critical insights into water's thermal properties.

PREREQUISITES
  • Understanding of thermodynamics principles
  • Familiarity with enthalpy and calorimetry
  • Knowledge of phase diagrams and their applications

What formula do I use the find :
1. How much energy is absorbed by water?

2. amount of heat produced per gram of fuel burned?

If it is regarding the fuel burning, you'll just use \Delta H; this value will give you how many calories are released as thermal energy; you'll divide this to the mole amount of compound to find the molar enthalpy. Then find the heat absorbance capacity of water by using a phase diagram.
