What is the specific heat of octane?
The specific heat of octane, C8H18 (l), is 2.22 J/g K.
What is heat of combustion of octane?
The heat of combustion of octane (C8H18, Mm = 114 g/mol) is -5500 kJ/mol.
What is the specific heat capacity of hexane?
2.26
Specific heat for some common liquids and fluids – acetone, oil, paraffin, water and many more
| Product | Specific Heat – cp – | |
|---|---|---|
| (kJ/(kg K)) | (Btu/(lb oF)) (Kcal/kg oC) | |
| Heptane | 2.24 | 0.535 |
| Hexane | 2.26 | 0.54 |
| Hydrochlor acid | 3.14 |
What is the specific heat value of methanol?
2.53
At ambient pressure and temperature the isobaric specific heat, CP, of liquid methanol is 2.53 [kJ/kg K] or 0.605 [Btu/lb °F] = [cal/g K], while the isochoric specific heat, CV, is 2.12 [kJ/kg K] or 0.506 [Btu/lb °F] = [cal/g K]. However, the specific heat – CP and CV – will vary with temperature.
What is the heat capacity of benzene?
Chemical, physical and thermal properties of benzene, also called benzol. Phase diagram included.
| Property | Value | Unit |
|---|---|---|
| Specific heat capacity, Cp (gas) | 82.4 | J/mol K |
| Specific heat capacity, Cp (liquid) | 133 | J/mol K |
| Specific heat capacity, Cp (solid) at 32°F/0°C | 118 | J/mol K |
| Specific heat capacity, Cv (liquid) | 92.8 | J/mol K |
How much heat is released by burning a gallon of octane?
Question: The thermal energy produced by burning one gallon of octane using 3.8L with a density of 0.70g/mL is 126, 646kJ.
What is the heat of combustion of methanol in kJ mol?
-723 KJ/mol
Heat of combustion of methanol CH3OH(l) is -723 KJ/mol at 298 and at constant pressure.
Which is the condensed structural formula for Octane?
Chemical compound. Octane is a hydrocarbon and an alkane with the chemical formula C 8 H 18, and the condensed structural formula CH 3 (CH 2) 6 CH 3. Octane has many structural isomers that differ by the amount and location of branching in the carbon chain.
Which is the standard value for Octane in gasoline?
One of these isomers, 2,2,4-trimethylpentane (commonly called iso-octane) is used as one of the standard values in the octane rating scale. Octane is a component of gasoline (petrol).
What is the specific heat of a liquid?
See also tabulated values for gases, food and foodstuff, metals and semimetals, common liquids and fluids and common solids, as well as values of molar specific heat for common organic substances and inorganic substances.
How is the octane rating of heptane determined?
The octane rating was originally determined by mixing fuels from only heptane and 2,2,4-trimethylpentane (a highly branched octane), and assigning anti-knock ratings of zero for pure heptane and 100 for pure 2,2,4-trimethylpentane. The anti-knock rating of this mixture would be the same as the percentage of the latter in the mix.
