Methane is a colorless, odorless, and flammable gas with the chemical formula CH4 and a molar mass of 16.043 g·mol−1. It is the simplest alkane and the main component of natural gas. Learn more about its properties, structure, and uses on Wikipedia.
Ethane is a colorless, odorless gas with the chemical formula C2H6. Its boiling point is −88.5 °C and its critical point is 305.32 K. Learn more about its history, chemistry, production, usage, health and safety on Wikipedia.
Climate sensitivity is how much Earth's surface will warm for a doubling in the atmospheric carbon dioxide concentration. Learn about the fundamentals, types, and methods of estimating climate sensitivity, and its societal importance for climate change mitigation.
where p is the vapor pressure, T is temperature (in °C or in K according to the value of C) and A, B and C are component-specific constants. The simplified form with C set to zero: = is the August equation, after the German physicist Ernst Ferdinand August (1795–1870). The August equation describes a linear relation between the logarithm ...
Reduced properties are dimensionless thermodynamic coordinates that describe the state of a fluid near its critical point. Reduced temperature is the actual temperature divided by the critical temperature, and it is used in equations of state and critical exponents.
The van der Waals equation is an equation of state that extends the ideal gas law to include the non-zero size and interactions of gas molecules. It can model the phase change, liquid vapor, and explain the critical point and the metastable states of fluids.
