Question

Отличие газа от плазмы?​

Answer 1

Ответ:

Плазма отличается от нейтрального газа и реакцией на внешние электрические и магнитные поля (обычный газ их практически не замечает). Частицы плазмы, напротив, чувствуют сколь угодно слабые поля и немедленно приходят в движение, порождая объемные заряды и электрические токи. Еще одна важнейшая особенность равновесной плазмы — зарядовое экранирование.

Difference between Gas and Plasma

Gas and plasma are two distinct states of matter with different properties. Here are the key differences between gas and plasma:

1. Composition: - Gas: A gas is composed of individual atoms or molecules that are not electrically charged. - Plasma: Plasma is composed of ionized gas, meaning that some or all of the atoms have lost or gained electrons, resulting in a mixture of positively charged ions and negatively charged electrons.

2. Electrical Conductivity: - Gas: Gases are generally poor conductors of electricity because the atoms or molecules are not ionized and do not carry an electric charge. - Plasma: Plasma, on the other hand, is an excellent conductor of electricity due to the presence of free-moving charged particles.

3. Energy Levels: - Gas: In a gas, the atoms or molecules have relatively low energy levels and move freely in random directions. - Plasma: Plasma has much higher energy levels compared to gas. The charged particles in plasma can move rapidly and exhibit collective behavior, such as the formation of electric and magnetic fields.

4. Temperature: - Gas: Gases can exist at a wide range of temperatures, from very low temperatures to extremely high temperatures. - Plasma: Plasma is typically formed at high temperatures, such as those found in stars or during high-energy events like lightning strikes.

5. Appearance: - Gas: Gases are usually colorless and transparent, although some gases may have distinct colors or odors. - Plasma: Plasma can emit light and display various colors, depending on the types of ions and electrons present.

6. Applications: - Gas: Gases have numerous practical applications, such as in heating, cooling, and as a fuel source. - Plasma: Plasma has applications in fields like fusion research, plasma cutting, plasma TVs, and certain medical treatments.

It's important to note that while the information provided above is based on general characteristics, there may be exceptions or additional details depending on specific contexts or scientific research.

I hope this helps clarify the difference between gas and plasma! Let me know if you have any further questions.
