are prime examples of the implementation of gas laws. The physics are based on the simple principle that warm air rises in cooler air. Hot air has less mass per unit of volume. The relevant gas law in use is Charless Law‚ which is V1/T1=V2/T2. The law states that raising the temperature (T1) will also increase the volume (V2)‚ in order to keep the equation true. Generally‚ air is heated through the use of propane burners. When ignited‚ the volume of the gas increases but the balloon cannot expand much

CHAPTER 1: NATURAL GAS IN INDIA * Importance of natural gas Natural Gas is a new age fuel. Natural Gas is the cleanest of fossil fuels. Natural Gas satisfies most of the requirements for fuel in a modern day industrial society‚ being efficient‚ non-polluting and relatively economical. Natural Gas requires a strong distribution network to not only support existing demand‚ but also fuel future demand. A big challenge lies in bridging the physical gap between demand and supply centers in an efficient

Case: Gas or Grouse? 1. Systemic issues: Questar is a company and it knows that every mining activities in Mesa will affect the ecological environment. But BLM did nothing since Questar had damaged the local environment. And we know many gas companies have special relationship with governments. Corporate issues: Questar has destroyed the environment when the mining operation was begun. Individual issues: The people who live in Pinedale Mesa believe the drilling activity bring numerous

when I think of price elasticity. Included in my list are fuel‚ cigarettes‚ electricity‚ and toilet paper. Price elasticity means that the behaviors of supply and demand are not affected when the price of that particular item rises (changes). Our local power companies experience price elasticity on the energy that we demand‚ when they continually raise prices but the amount of consumer usage is unaffected. In some parts of the country their may be alternatives such as gas heat and fire places

Plant derives their power from gas burning. LNG Power Plant can use gas engine or gas turbine as their power generating unit. Generally gas turbine design for simple & combine cycle with rugged components for base load utility service but also can start & stop easily for peaking application. In the other hand‚ gas engine design for wide variety of application‚ and provide fast and flexible capacity with multiple unit. This comparation of gas engine and gas turbine advantages and disadvantages
