Nanoparticles often have different properties than the bulk material due to increased surface area which results in higher reactivity, quantum effects which alters the electrical and visual properties due to confinement of electrons which changes the wavelengths absorbed as well as the conduction band gap.
A chemical reaction causes substances to combine in different ways to make other substances.
Impure substances are materials made up of molecules that are not uniform throughout . Impure substances can be seperated into different materials. Mixtures are impure substances. It could be either heterogeneous mixture or homogeneous mixture.
Substances are classified into two main categories: pure substances and mixtures. Pure substances consist of a single type of particle and can be further divided into elements and compounds. Mixtures, on the other hand, contain two or more different substances that retain their individual properties and can be homogeneous (uniform composition) or heterogeneous (distinct phases). This classification helps in understanding the properties and behaviors of different materials in chemistry.
They substances transported by blood.Gases,Nutrients,Water,Hormones,Urea,Ammonia,Other waste materials etc.
A chemist is a person whose job involves studying substances and the changes they undergo when combined to create new substances. They analyze the properties and reactions of different materials, conducting experiments to understand chemical processes. Chemists work in various fields, including pharmaceuticals, environmental science, and materials science, applying their knowledge to develop new products and solutions.
Opaque substances that are used to color other materials are called pigments. Some call them dyes.
Substances used to color other materials are called pigments. Pigments can be organic or inorganic compounds and are finely ground to produce different colors. They are commonly used in paints, inks, plastics, and cosmetics to provide the desired color.
A chemical reaction causes substances to combine in different ways to make other substances.
Eco footwear is footwear that is environmentally friendly and safe. They are made from recycable materials, vegan substances and/or non-toxic substances that do not hurt the environment while in production.
materials usually expand when heated.
Impure substances are materials made up of molecules that are not uniform throughout . Impure substances can be seperated into different materials. Mixtures are impure substances. It could be either heterogeneous mixture or homogeneous mixture.

Oxidising hazardous substances are materials that can cause or enhance the combustion of other materials by providing oxygen or other oxidizing agents. These substances can react vigorously with flammable materials, leading to fires or explosions. They are classified as hazardous due to their potential to pose significant risks to health and safety during handling, storage, and disposal. Proper precautions and regulations are essential when working with or around these substances to mitigate their dangers.

an orthotropic material is one that has the different materials properties or strength in different octhogonal directions, but properties of anisotropic material being directionally dependent. thus Orthotropic materials are anisotropic.
