Burning point

To ascertain whether the powders, os usually manufactured, actually do ignita at the burning point of sulphur, VroLETTE made some examinations by placing portions of the powder to bo tested on. the surface of a bath of tin, in which the bulb of a thermometer was immersed, the whole being heated by a small carcel-lamp the following results were obtained—... 

FLASH POINT. The lowest temperature at which an oil will volatilize to yield sufficient vapor to form with air an inflammable gaseous mixture, demonstrable through the production of a flush on comacl w ith a small open Hume. The flash point occurs at a temperature lower than the burning point, w hich is the lowest temperature at which the production of combustible gas occurs rapidly enough in support a steady flame. It is also m be noted that the flash point is the temperature of formation, under the test conditions, of the losver explosive mixture of the substance tested, with air. iThc higher explosive mixture is the maximum concentration of vapor, with air. which will sustain combustion.)... 

These papers are stealth helpers in the baking kitchen. When you cut them out to fit the bottom of a baking pan, they ensure that your cake will not stick to the bottom. Parchment paper has a higher burning point than wax paper, so use it for baking cakes or cookies. Wax paper is the perfect place to lay cookies that have just been dipped in chocolate. 

Mechanical working of a metal is plastic deformation performed to change dimensions, properties, and/or surface conditions. Plastic deformation below the rectys-tallization temperature is called cold working. Plastic deformation above the recrystallization temperature, but below the melting or burning point, is called hot working. 

Crude oil is a substance which emerges from the ground as a thick, viscous, brown or dark green liquid. Some types like the deposits of Venezuela, contain primarily gasolines. Others, like those of Texas, are richer in fuel-oil while others like those of Mexico contain more bitumen for asphalt. The specific gravity varies and provides an indication of quality. Other criteria include pour- and cold-points, viscosity, optical properties, odor flash- and burning-points, color and coefficient of expansion. 

Since petroleum is a mixture, its physical properties vary considerably, depending upon the type and proportions of the hydrocarbons and impurities present. These physical properties include the density, viscosity, optical activity, refractive index, color, fluorescence, odor, pour- and cold-points, flash- and burning-points, coefficient of expansion, surface and interfacial tension, capillarity and absorption. 

Cloud-point—temperature where solid paraffin waxes settle out Pour-point—lowest temperature where oil is fluid Flash-point—temperature where vapors will flash ignite Burning- point—temperature where oil will burn with a steady flame... 

The flash and burning points are key to the hazards involved in storing and handling the oil. The others are important in transportation of the oil. Pour-points can vary from 90°F to 70°F and lower. 

Floor system.—In this method the damp cereal is spread upon the floor and is periodically shovelled over to aerate the germinating mass and keep its temperature below the scorching or burning point. The right air temperature is about 6o° F. and the grain temperature should be about 750 F. 

Of course, if the quantity of water thrown upon a fire is not sufficient to abstract from the fire, by its conversion into steam, heat enongli to reduce the temperature of the whole mass of burning materials below the burning-point, it will m>t cxtingui.ch tlie fire. 

Burning Point - The temperature at which a material ignites. 

Simprosys is applied to the drying of a solid material containing ethanol. Due to the low flash (burning) point,...
