Propane

Propane is a hydrocarbon gas with the chemical formula C3H8. It is a colorless and odorless gas at standard temperature and pressure, but it is typically compressed and stored as a liquid. Propane is commonly used as a fuel for heating, cooking, and powering vehicles and equipment.

Physical Properties of Propane

Propane has a boiling point of -42 degrees Celsius and a melting point of -187 degrees Celsius. It is highly flammable and burns in the presence of oxygen to produce carbon dioxide and water vapor. Propane has a density of 1.89 kg/m^3 as a liquid and 1.88 kg/m^3 as a gas at 25 degrees Celsius and 1 atmosphere of pressure.

Chemical Properties of Propane

Propane belongs to the alkane family of hydrocarbons, which are characterized by single bonds between carbon atoms. When combusted, propane undergoes a chemical reaction with oxygen to release energy in the form of heat and light. The balanced chemical equation for the combustion of propane is:

C3H8 + 5O2 → 3CO2 + 4H2O

Uses of Propane

Propane is used as a fuel for a wide range of applications, including:

• Heating homes and buildings
• Cooking and grilling
• Powering vehicles and engines
• As a refrigerant in the form of propane gas
• As a propellant in aerosol sprays
