State of matter is one of the tree physical states in which matter can exist, i.e. solid, liquid or gas. Plasma is sometimes regarded as the fourth state of matter. By means of heating a solid substance will cross to liquid state at its melting point. If we heat up a liquid and beyond, at its boiling point it will cross to gaseous state - vapour.
Foreign matter most commonly refers to the presence of unwanted or undesirable material present in foods or chemicals.
Miscible matter is capable of being mixed in any ratio with another matter without separation of two phases.
Optically active matter, by polarized light passing through it, turns the flat of polarized light leftwards or rightwards.
Change of state is a physical change which appears when a substance crosses from one state into another. This usually happens because of the change of energy of particles provoked by heating or cooling.
Liquids have a constant volume, but they do not have a constant shape. They assume the shape of a vessel they are in at the moment. It happens because molecules of liquids are still close enough to each other, the attracting forces still being very strong.
Solid state is characterised by a constant shape and volume. Particles are placed very close to one another and have efect one on another with great attraction forces. Solid bodies do not assume the shape of the container in which they are put.
Equation of state is an equation relating the pressure, volume, and temperature of a substance or system. Equation of state for ideal gas
where p is pressure, V molar volume, T temperature, and R the molar gas constant (8.314 JK-1mol-1).
Nascent state is an especially active state of an element in a moment when it is released from a compound during chemical reaction, e.g. nascent hydrogen.
