Answer» Answer: (1)- Lightning is a discharge of electricity. ... A single stroke of lightning can heat the air around it to 30,000°C (54,000°F)! This extreme heating causes the air to expand explosively fast. The expansion creates a shock wave that turns into a booming sound wave, known as thunder(2)- The conductor and insulator are the types of MATERIAL. ONE of the major difference between the conductor and insulator is that the conductor ALLOWS the ENERGY (i.e., current or heat ) to pass through it, whereas the insulator does not allow the energy to pass through it(3)-Word forms: plural lightning conductors. countable noun. A lightning conductor is a long thin piece of metal on top of a BUILDING that attracts lightning and allows it to reach the ground safely. [British]regional note: in AM, use lightning rod. |
