This is False. The colour has to change to be a chemical change/property. If it stays the same, it is physical. Hardness is an example of a physical property. (ex. If I melt a piece of hard steel, it will become soft, liquid probably, but it isn't hard anymore, this change is reversible, therefore a physical change/property)
Physical matter, of course. :) Saying this cause I just took a bio test. Good luck. x
Wood is mainly composed of cellulose, hemicellulose, and lignin. These components give wood its strength, flexibility, and resistance to decay. Different types of wood have varying proportions of these constituents, leading to differences in properties such as hardness, density, and color.
A chemical reaction is a process in which one or more substances are converted into different substances with new chemical properties. This involves the breaking and forming of chemical bonds between atoms. Characteristics of a chemical reaction include changes in energy, color, temperature, or the formation of new products.
Density is a trait of a substance by itself. It is a physical property that describes the compactness of a substance and is independent of the amount of the substance present.
A phenotype (from Greek phainein to 'show' + typos 'type') is an organism's observable characteristics or traits: such as its morphology, development, biochemical or physiological properties, behavior, and products of behavior (such as a bird's nest). Simple examples include hair color, eye color, height, pelt color.
Color, texture, and hardness are examples of physical properties. Shape and size are two more examples.
Physical properties of a substance.
Color, mass, volume, density, hardness, and ductility
Physical properties.
The properties of a mineral are primarily the result of its chemical composition and atomic structure. These factors determine characteristics such as color, hardness, cleavage, and crystal form in a mineral.
Rocks are classified based on their mineral composition, color, texture, and hardness. They can be categorized as igneous, sedimentary, or metamorphic based on how they were formed. Rocks can vary in density, porosity, permeability, and can exhibit different physical and chemical properties.
Physical change is the change in which only physical properties changes ,like color, hardness, density etc. Chemical changes affect the composition as well as chemical properties of matter and result in formation of new substance. Examples of chemical changes are : Burning of coal Burning of Paper Electrolysis of water
chemical properties are to do with how it acts chemically- so: polar vs Non polar PH / Pka melting point / boiling point Therefore non-examples would be its molecular mass/ geometry / atomical structure... although some of these would surely contribute to its chemical properties.
color, hardness, chemical composition, system of crystallization, refractive index, luster, magnetic properties, radioactivity, fracture characteristics, etc.
Examples: chemical composition, absorption spectra, crystallographic data, X-ray diffraction data, density, melting point, hardness, color, odor and many others.
7 Properties include: Hardness, luster, streak, cleavage, density, color, and fracture.
Examples: density, refractive index, color, thermal conductivity, melting point, hardness etc.
