The data about butane density over a range of temperature [−50; +50] °C [4] Vapor pressure of liquid. ... Vapor pressure of n-butane. From formula: ...
The density of butane is highly dependent on temperature and pressure in the reservoir. [19] For example, the density of liquid butane is 571.8±1 kg/m 3 (for pressures up to 2 MPa and temperature 27±0.2 °C), while the density of liquid butane is 625.5±0.7 kg/m 3 (for pressures up to 2 MPa and temperature −13±0.2 °C).
The autoignition temperature or self-ignition temperature, often called spontaneous ignition temperature or minimum ignition temperature (or shortly ignition temperature) and formerly also known as kindling point, of a substance is the lowest temperature at which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark.

The constant volume adiabatic flame temperature is the temperature that results from a complete combustion process that occurs without any work, heat transfer or changes in kinetic or potential energy. Its temperature is higher than in the constant pressure process because no energy is utilized to change the volume of the system (i.e., generate ...
Radiography reveals the type, condition and density of the wood, as well as any pest damage or activity. [18] [19] Furniture and Larder Beetles [20] can burrow into wood compromising its internal structure and should be treated before proceeding with the restoration. IR, raking light photography, and low-magnification observation are useful in ...
Such measurements often use a standard temperature of 25 °C (77 °F; 298 K) [citation needed]. This is the same as the thermodynamic heat of combustion since the enthalpy change for the reaction assumes a common temperature of the compounds before and after combustion, in which case the water produced by combustion is condensed to a liquid.
Increased heat from light creates paint soften: 68 °F ± 2° High temperature softens paint. low temperature causes brittle paint. Oil Paint [23] 40–45% or 45–45%: Expansion and contraction of painting, wood and fabric absorb moisture or shrink, paint cracks and flakes, or sags: max 200 lux: Fading or darkening of painting
