¿Qué es el Plasma? - Propiedades de la Materia

The video tutorial explores the states of matter, starting with the traditional three: solid, liquid, and gas. It explains the transitions between these states, such as melting and evaporation. The tutorial then introduces plasma as the fourth state of matter, detailing its unique properties, such as electrical conductivity. Examples of plasma in nature, like lightning and stars, and in technology, such as plasma screens and neon signs, are discussed.

What happens to the particles in a solid when it changes to a liquid?

• They become tightly packed.

• They move farther apart and take a fixed shape.

• They start moving around each other.

• They become electrically charged.

What is required for a gas to transform into plasma?

• Compressing the gas into a solid.

• Cooling the gas to a low temperature.

• Applying very strong heat.

• Mixing the gas with a liquid.

What is the main difference between a gas and plasma?

• Gas particles are charged, while plasma particles are not.

• Plasma can conduct electricity, while gas cannot.

• Plasma is cooler than gas.

• Gas has a fixed shape, while plasma does not.

Which of the following is a natural example of plasma?

• Carbon dioxide

• Lightning

• Ice

• Water vapor

How do plasma screen TVs create different colors?

• By using a liquid crystal display.

• By using a single fluorescent light.

• By combining red, green, and blue light electrodes.

• By heating gases to a high temperature.
