WebDescription. The Rankine cycle closely describes the process by which steam engines commonly found in thermal power generation plants harness the thermal energy of a fuel or other heat source to generate electricity. Possible heat sources include combustion of fossil fuels such as coal, natural gas, and oil, use of mined resources for nuclear fission, … WebVapour pressure is directly proportional to temperature. This means that when we increase the temperature, a significant and proportionate increase in the formation of vapours can be observed, which further increases the vapour pressure. Examples of Vapour Pressure 1. Tea Kettle 2. Humid Air 3. Smell of Brandy or Whisky 4. LPG Cylinders 5.

Web12 sep. 2024 · The enthalpy of reaction is defined as the internal energy of the reaction system, plus the product of pressure and volume. It is given by: H=U+PVH=U+PV. By adding the PV term, it becomes possible to measure a change in energy within a chemical system, even when that system does work on its surroundings. Web26 mrt. 2016 · Fire, heat of solution, boiling, chemical cold packs, freezing. Explanation: Enthalpy is the word for energy. It includes molecular potential energy as well as the exchange of heat energy between different compounds or systems. Here is a video that introduces the concept of enthalpy. Answer link
