Chapter 4: Energy from CombustionThe primary means of generating Energy for humanendeavors is the Combustion of :Coal-burned in power plantsGasoline-burned in automobilesNatural gas-heatingHeating oil , charcoal,wood,candles,.. Combustion (burning in air) releases thechemical energystored in the chemical bondsof the rate of use/consumption of fuels is fossil fuels supply is not fuels took millions of years to produce and products from the burning of fuels adversely affectthe soot, CO, Hg,SOx,NOx global warming, acid rain, poor air and water governing Energy transformation from limitation of converting all Energy in a fuels tousable content of different fuels (made up of differentchemical compounds).
The potential energy stored in fossil fuels are the sun’s energy captured, millions of years ago by plants. Energy is the capacity to do work. Work is movement against a force (w = f × d). Definitions: Heat is energy that flows from a hotter to a colder object. Temperature determines the direction of heat flow. 4.1
