B neon signsneon signs
C microwave ovensmicrowave ovens
D all of these
D all of these
To determine in which of the given options plasma can be found, let's discuss what plasma is first. Plasma is one of the four fundamental states of matter, along with solid, liquid, and gas. It is an ionized gas, consisting of particles that have been stripped of their electrons.
Now, let's go through each option to determine if plasma can be found in them:
A) Lightning: Yes, plasma can be found in lightning. Lightning is a natural electrical discharge that occurs during thunderstorms, and it is formed by the movement of electrically charged particles, which creates a plasma channel.
B) Neon signs: Yes, plasma can be found in neon signs. These signs contain gas, usually neon or other noble gases, at low pressure. When an electric current passes through the gas, it ionizes the particles, creating glowing plasma discharge.
C) Microwave ovens: No, plasma is not typically found in microwave ovens. Microwave ovens generate microwave radiation to heat food by exciting water molecules, but they do not produce plasma.
Based on the above analysis, the correct answer is D) all of these. Plasma can be found in lightning and neon signs, but not in microwave ovens.
