When wood is completely dry and is not a type of artificial wood, the combustion temperature is generally 451 degrees Fahrenheit, according to the Argonne National Laboratory. However, there are many variables, such as moisture, oxygen ability and wood density, that come into play.Know More
If wood has any moisture on or within it, it can take longer for it to catch fire. This is why it is important to find dry sticks and leaves when creating a fire. The amount of oxygen is important because oxygen is necessary to start and grow a fire. The type of wood and the size of the wood also factor in. Wood that is denser releases more heat, burns hotter and burns slower because it has a high energy content. Examples of dense wood include oak and maple.
With size, the wood should fit into the burning appliance, and one should be able to stoke it without difficulty. Stoking allows one to maintain a fire. On average, 3 inches in length is ideal for furnaces and stoves, while 14 to 18 inches in length is ideal for fireplaces.Learn more about States of Matter
To remain in its solid phase, dry ice must be kept at temperatures lower than -109.3 degrees Fahrenheit. At higher temperatures, dry ice begins to sublimate, or turn directly from a solid into a gas.Full Answer >
A bonfire built with wood and charcoal can burn at temperatures up to 2,012 degrees Fahrenheit. The color of the fire is an indicator of temperature; dark red flames are cooler at 1,112 degrees F than orange-yellow flames at 2,012 degrees F.Full Answer >
Water reaches its maximum density at around 39 degrees Fahrenheit. When water either cools or heats beyond this point, it becomes less dense. Although most ice floats on water, heavy ice is composed of an isotope of hydrogen known as deuterium and sinks as a result of its heightened density.Full Answer >
Chemists at the University of Utah discovered that ice forms at temperatures as low as minus 55 degrees Fahrenheit, according to a Science Daily article. Prior to this discovery, scientists believed ice formed exclusively at 32 degrees Fahrenheit.Full Answer >
