Answer:
G. it enables people to use pots and pans made of metal to cook food
Explanation:
Metals are known to be substances with a relative high melting point, which means that it takes a very high temperature to melt them. As used in this question, copper (Cu) and iron (Fe) at metallic elements that have high melting points.
One advantage of this property based on the options provided is that "it enables people to use pots and pans made of metal to cook food". This is because cooking food requires subjecting them to a constant temperature from a heat source e.g cooker or stove.
The material used to hold the food being cooked must possess a very high melting point to withstand the heat, hence, the importance of these metallic substances. Most pots and pans are made of steel, an alloy of iron, hence, they have high melting point.
I believe it’s A, i could be wrong tho 3
<span>The answer is a width of a textbook. It is usually has centimeter
and millimeter units on it. Since rulers are most commonly 15 or 30 cm long, it
could only be used to measure the length or width of small things like small
tin, or the length of a piece of paper. A length of a river and the distance between two cities cannot be measured by a ruler, there is proper equipment for that, the same goes for the size of an object under the microscope. </span>
