Is a tree burning to form ashes a physical or chemical change?
The process of a tree burning to form ashes is a chemical change. This is because the chemical composition of the tree is altered as it undergoes combustion, transforming into new substances such as carbon dioxide, water vapor, and ash.
Is a tree burns to form ashes chemical change?
The parts of the tree that burn are undergoing a chemical change. The ashes remaining may or may not have undergone a chemical change, depending on the the chemical bonding that the atoms in the ash had before the tree was burned.
What is color of peat?
Peat is typically dark brown to black in color, depending on its age and composition.
How does the peat scale measure the quality and quantity of peat in a given area?
The peat scale measures the quality and quantity of peat in a given area by assessing factors such as moisture content, organic matter composition, and thickness of the peat layer. This scale helps researchers and environmentalists understand the value and potential uses of peat in a specific location.
Is a burning wood into ashes and smoke a physical or chemical change?
Burning wood is a chemical change - although, like most chemical changes it is accompanied by a physical change. Usually we reserve the term physical changes for things like erosion, melting, or evaporation where no change in composition occurs.
What mineral has a structure and a chemical composition that indicate the conditions under which it formed?
Garnet is a mineral that can exhibit distinct zoning patterns that can provide information about the changing conditions during its formation. This can include changes in temperature, pressure, and composition within the environment where the garnet crystals grew.
What is the chemical composition of peat?
The peat in the world's peatlands has been forming for 360 million years and contains 550 Gt of carbon. Under the right conditions, peat is the earliest stage in the formation of coal. Peat forms when plant material, usually in marshy areas, is inhibited from decaying fully by acidic and anaerobic conditions. It is composed mainly of marshland vegetation: trees, grasses, fungi, as well as other types of organic remains, such as insects, and animal corpses. Under certain conditions, the decomposition of the latter (in the absence of oxygen) is inhibited, and archaeologists often take advantage of this. -Mickey (+63-921-667-0-667)
When water evaporates its chemical composition?
The chemical composition remain unchanged.
When you fry an egg is that a physical change or chemical change?
It is a chemical change because you can't change a fried egg into it's original, uncooked form. Like a log burned into ashes. You can't get ashes to change into it's own self - wood.
What is the texture of peat?
Peat typically has a spongy and fibrous texture due to its composition of decomposed organic matter, such as mosses and plants. It can feel dense and compact when compressed, but crumbles easily when dry.
What is the diffence between physical and chemical properties as well an physical and chemical changes?
Physical properties can be observed without changing the chemical composition of a substance. Chemical properties can only be observed by changing the chemical composition of the substance. In a physical change, the chemical composition of the substance does not change. In a chemical change, the chemical composition of the substance changes.
What is the flashpoint temperature of peat?
The flashpoint temperature of peat can vary, but it generally ranges between 200 to 300 degrees Celsius (392 to 572 degrees Fahrenheit). This temperature indicates the point at which peat can ignite in the presence of an open flame or spark. Factors such as moisture content and composition can influence the specific flashpoint of different peat samples.
