Some common insulator<span> materials are glass, plastic, rubber, air, and wood. </span>Insulators<span> are used to protect us from the dangerous effects of electricity flowing through conductors. Sometimes the voltage in an electrical circuit can be quite high and dangerous.
Hope this helps :)</span>
Answer:
An example of this event is hypothermia, where blood pressure decreases and the blood vessels constrict, while in hyperthermia, the blood pressure increases and the blood vessels dilate.
The third choice is the answer.
This is because chemical change occurs when the (for a lack of better wording) interior of the object is changed in the second one the bread is being broken down chemically by the stomach acid this is because the acid is breaking down the formation of the bread dissolving it and chainring it into something else.
In the 4th one the change that is seen is chemical because the formation of the roof is change the physical appearance may be the same (ie. The size & shape) but their are other changes in the color, texture and maybe taste ( don’t taste a rusting roof lol) these are ways in which you can figure out if a change is chemical or physical.
Physical change occurs when the size and/or shape of an object is changed.
Chemical change occurs when the texture, taste and/or color of the object is changed, but-sometimes chemical change cannot be seen.
Hope this helped :)
Answer:Silver
Explanation:Silver has the highest electrical conductivity of all metals. In fact, silver defines conductivity - all other metals are compared against it. On a scale of 0 to 100, silver ranks 100, with copper at 97 and gold at 76.
