Methane — what is it? Methane is a chemical substance that is nearly half as dense as air. The mass of 1 m³ of methane at 0°C and a pressure of 760 mmHg is 0.717 kg. Its molecular formula, CH₄, indicates that a methane molecule consists of one carbon atom ...

What is ethane? Ethane is a complex gaseous substance that is heavier than air. The mass of 1 m³ of ethane at 0°C and a pressure of 760 mmHg is 1.357 kg. Its molecular formula is C₂H₆, meaning that an ethane molecule consists of two carbon atoms and six hydrogen ...

Propane — what is it? Propane is a complex chemical substance that is more than twice as heavy as air; 1 m³ of propane weighs 2.604 kg. Its molecular formula is C₃H₈, meaning that a propane molecule consists of three carbon atoms and eight hydrogen atoms. Its autoignition temperature is ...

Butane — what is it? Butane is a complex chemical substance that is more than twice as heavy as air. One cubic meter (1 m³) of butane weighs 2.703 kg. Its molecular formula is C₄H₁₀, meaning that a butane molecule consists of four carbon atoms and ten hydrogen atoms. Its ...

Which gases are classified as heavy hydrocarbons? Heavy hydrocarbon gases with the formula (СпН2п+2) include: ethane (С2Н6), propane (С3Н8), butane (С4Н10) – like methane, they have no color, odor or taste, and are non-toxic. Their physical properties depend on their molecular weight. The larger the μ, the higher the density ...

Rauschenbach – Vibrational Combustion Rauschenbach’s book, “Vibrational Combustion,” systematically presents a modern theory of the excitation of longitudinal acoustic oscillations by heat supply. The laws inherent in this type of oscillation are examined, with their analysis drawing extensively on information from fluid mechanics, combustion acoustics, and the theory of control ...
