In thermodynamics, the enthalpy of vaporization (symbol ∆Hvap ), also known as the ( latent) heat of vaporization or heat of evaporation, is the amount of energy ( enthalpy) that must be added to a liquid substance to transform a quantity of that substance into a gas. The enthalpy of vaporization is a function of the pressure and temperature ...
Heat of combustion. The heating value (or energy value or calorific value) of a substance, usually a fuel or food (see food energy ), is the amount of heat released during the combustion of a specified amount of it. The calorific value is the total energy released as heat when a substance undergoes complete combustion with oxygen under standard ...
Propane has lower volumetric energy density, but higher gravimetric energy density and burns more cleanly than gasoline and coal. [6] Propane gas has become a popular choice for barbecues and portable stoves because its low −42 °C boiling point makes it vaporise inside pressurised liquid containers (it exists in two phases, vapor above liquid).
Liquefied petroleum gas. Liquefied petroleum gas, also referred to as liquid petroleum gas ( LPG or LP gas ), is a fuel gas which contains a flammable mixture of hydrocarbon gases, specifically propane, n -butane and isobutane. It can sometimes contain some propylene, butylene, and isobutene. [1] [2] [3]
Material Safety Data Sheet. Propane does not have health effects other than the danger of frostbite or asphyxiation. The National Propane Gas Association has a generic MSDS available online here. (Issued 1996) MSDS from Suburban Propane, L.P dated 5/2013 in the SDSdata.org database. This box:
In other words, its potential energy is zero. Hence, all the energy possessed by the gas is the kinetic energy of the molecules, or atoms, of the gas. = This corresponds to the kinetic energy of n moles of a monoatomic gas having 3 degrees of freedom; x, y, z. The table here below gives this relationship for different amounts of a monoatomic gas.
Inergy. Inergy, L.P. ( NYSE : NRGY) is an American supplier of propane based in Kansas City, Missouri that claims to be the fourth-largest propane retailer in the United States. Serving 800,000 customers in 28 states. [1] [2] It is also a major salt miner via its U.S. Salt LLC subsidiary with its salt caverns later being used for natural gas ...
In chemistry and thermodynamics, the standard enthalpy of formation or standard heat of formation of a compound is the change of enthalpy during the formation of 1 mole of the substance from its constituent elements in their reference state, with all substances in their standard states. The standard pressure value p⦵ = 105 Pa (= 100 kPa = 1 ...
