Water is a good conductor of electricity, so coming into contact with water while electricity is present can result in a dangerous shock. Other conductive materials, such as metal, can also cause a dangerous shock when in contact with electricity.
A substance that does not permit the passage of x-rays or other radiant energy is characterized as being opaque. This means that the substance absorbs or scatters the radiation, preventing it from passing through. Examples of opaque materials include lead and thick concrete.
Wood, plastic, glass, paper, and cotton are examples of materials that are not magnets. These materials do not have magnetic properties and do not attract or repel other magnetic materials.
Most substances are not attracted to magnets. The only substances that are typically attracted to magnets are ferromagnetic materials such as iron, nickel, and cobalt. Some other materials, like certain alloys or compounds, may also exhibit magnetic properties.
Materials that attract other materials after rubbing are called "static electricity generators" or "triboelectric materials." When two different materials come into contact and are then separated, they can create a charge imbalance, resulting in one material attracting the other due to this imbalance. This phenomenon is known as triboelectric effect.
This substance is called solvent,.
The substance that dissolves other substances is known as the solvent. It is usually a liquid, such as water, in which other materials can be dissolved to form a solution.
Solvent
It is said to be water soluble. Other materials may be soluble in oils, aromatic hydrocarbons, or chlorinated compounds.

A type of mixture that is formed when one substance dissolves into another and fills the spaces between other kinds of molecules is called colloidal solution.
Hot fluid dissolves materials and adds other materials :)
A homogeneous mixture is formed when one substance dissolves into another and fills the spaces between other kinds of molecules. This type of mixture has a uniform composition throughout, with the dissolved particles evenly distributed in the solvent.
The material in which another substance dissolves is called a solvent. A solvent is typically a liquid, but can also be a gas or a solid. It is capable of dissolving one or more other substances to create a homogeneous mixture known as a solution.
Solubility is the ability of a substance to dissolve completely in another substance. The substance that dissolves is called the solute. If the solute has a high solubility, then it easily dissolves in most substances to create a solution. If the solute has a low solubility, then it does not dissolve easily and rarely goes into solution with other substances.
solvent e.g hot water dissolves the solute (coffee powder) to make the solution instant coffee so the solvent is what dissolves the solute
