The definition teaches us: plasma is a set of quasi-neutral particles with free electric charge carriers, which behave collectively. Let us analyze each part of this definition. The most important part is that free electric charge carriers are found in the plasma state of matter. Atoms are at least partially ionized. The degree of ionization does not have to be too large, if the size of the plasma formation is big enough. Precisely a plasma is different from a gas in that there are free carriers of charge in the former. A plasma is conductive and reacts strongly to electric and magnetic fields. The second quality is its quasi-neutrality. Let us assume a certain volume, which microscopically shows in average the same quantity of positive and negative particles. Seen from the outside, the plasma behaves as if it were a fluid without charge (liquid or gas). The demanding of quasi-neutrality excludes the beams of charged particles from the definition of plasma. The last part of the definition of plasma is its collective behaviour. With this it is understood that plasma as a whole is capable of processes that generate electric and magnetic fields to which plasma can react in turn. The plasma definition does not include the beams of charged particles since they do not fulfill the requirement of quasi-neutrality. Neither are included the very weekly ionized gases, like the flame of a candle (they do not fulfill the requirement of collective behaviour). The plasma concept was used for the first time by Irwing Langmuir(1881-1957).
What else can I help you with?
What is plazma physics?
Q: What is plasma physics? not plazma. A:Matter assumes the state of gas, comprising of ions and electrons, at a very high temperature. This is called plasma. The study of properties of matter in this state is called plasma physics.
What is the significance of ion saturation current in plasma physics and its impact on plasma behavior?
Ion saturation current in plasma physics is significant because it represents the maximum current that ions can carry to a surface in a plasma. This current affects the behavior of the plasma by influencing the charging of surfaces and the overall balance of charge in the system. Understanding and controlling ion saturation current is crucial for manipulating plasma properties and optimizing plasma-based technologies.
What is the significance of the electron thermal velocity in the context of plasma physics?
The electron thermal velocity is important in plasma physics because it determines how fast electrons move due to their temperature. This velocity affects various plasma phenomena, such as energy transfer and wave propagation, making it a key parameter in understanding and analyzing plasma behavior.
what branch of physics deals with ionized gas?
The most obvious answer is, of course, Plasma physics; there are many other areas where ionised gases are potentially used. However, since a plasma is a form of ionised gas, this is the one which is clearly the most relevant.
What is the study of plasma- physics?
Plasma physics is the study of a state of matter in which gas molecules are stripped of their electrons, resulting in a collection of positively charged ions and free electrons. This field explores the behavior, properties, and dynamics of plasmas, which are commonly found in stars, lightning, and some man-made devices like fusion reactors. Plasma physics is crucial in understanding natural phenomena and developing technologies such as plasma TVs and particle accelerators.

What is the principle behind thompson scattering and how is it used in the study of plasma physics?
Thomson scattering is a process where electromagnetic radiation is scattered by free charged particles. In plasma physics, it is used to measure the properties of plasma, such as temperature and density, by analyzing the scattered light. This technique helps researchers understand the behavior of plasma in various conditions, such as in fusion experiments or astrophysical environments.
What is plasmology?
Plasmology is the scientific study of plasma, which is the fourth state of matter where gas becomes ionized. It involves understanding the properties, behavior, and applications of plasma in various fields such as physics, chemistry, and engineering. Plasma is commonly found in stars, lightning, and fluorescent lights.
Do plasma molecules have a strong attraction to each other?
Yes, plasma molecules have a weak attraction to each other due to electrostatic forces. The presence of charged particles in plasma leads to interactions that can result in collective behavior, such as waves and oscillations.
HOW create plasma from rotating electromagnetic field?
Plasma can be created from a rotating electromagnetic field by subjecting a gas to high temperatures and pressures within the field. The high-energy collisions between gas particles can then ionize the gas, turning it into a plasma. This process is often used in plasma physics experiments to study the behavior of plasma.
Is plasma same in physics and in chemistry?
No.
How does ensemble physics contribute to our understanding of complex systems in the field of theoretical physics?
Ensemble physics in theoretical physics helps us understand complex systems by studying the behavior of multiple interacting components as a whole. By analyzing the collective behavior of these components, we can gain insights into the overall dynamics and emergent properties of the system. This approach allows us to make predictions and draw conclusions about the system's behavior that would be difficult to achieve by studying individual components in isolation.
What is plasma theory?
Plasma theory is a branch of physics that studies the behavior and properties of plasma, which is a state of matter similar to gas but composed of charged particles. It seeks to understand phenomena such as plasma oscillations, instabilities, and interactions with electromagnetic fields. Plasma theory has applications in various fields, including astrophysics, fusion research, and plasma processing technologies.
