ainevaldkond
Ainevaldkond, also known as the "state of matter," refers to the physical form that a substance can take. There are four primary states of matter: solid, liquid, gas, and plasma. Each state is characterized by distinct properties such as volume, shape, and molecular arrangement.
In the solid state, particles are closely packed and have a fixed shape and volume. This state
Liquids have a fixed volume but take the shape of their container. The particles are more loosely
Gases have neither a fixed shape nor a fixed volume. The particles are widely spaced and move
Plasma is the fourth state of matter, consisting of a gas-like substance with a significant proportion of
The transition between states of matter can occur through changes in temperature or pressure. For example,
