Metals are good for tools because they are durable. Metals won't break while you are working hard throughout the day.
Igneous rocks are useful because they provide information about Earth's history, such as how they were formed and the conditions of their formation. They also contain valuable resources like metals and minerals. Additionally, igneous rocks are used in construction materials and as decorative stones.
Iron in hemoglobin makes it possible for animals to use oxygen to produce energy. Magnesium in chlorophyll makes it possible for plants to use sunlight to make sugars and to grow. there are other examples. vitamin b-12 et. al.
Earthquake simulators are useful tools because they allow scientists and engineers to study the effects of earthquakes on structures without having to wait for a real earthquake to occur. This can help in designing and constructing buildings that are better able to withstand seismic activity. Additionally, earthquake simulators can be used to test the effectiveness of different earthquake-resistant technologies and building materials.
Iron is a metal because it has metallic properties such as being malleable, ductile, and having luster. Sulfur is a non-metal because it tends to gain electrons in chemical reactions, forming negatively charged ions, and it lacks the luster and malleability of metals.
Crude oil in its natural state is not very useful because it contains impurities such as sulfur, nitrogen, and metals that need to be removed before it can be turned into usable products like gasoline, diesel fuel, and plastics. Additionally, crude oil needs to be refined to separate it into different components with specific properties.
Alloys are useful improvement over pure metals because they tend to be stronger.
Magnifying tools are useful because the object you are magnifying zoom in better and get more detail just like a microscope.
because they are using acids because they are using acids
Metallurgy began because early humans discovered that certain rocks could be heated and shaped into useful tools and objects. This led to the development of smelting techniques to extract metals from ores, allowing for the creation of more durable and versatile tools and weapons. Over time, metallurgy evolved as humans learned to manipulate different metals for various purposes.
Borax because it is made to use balls
They come into useful things from metals come i to use
there are many tools to mark metals with. Common tools to mark metals with include chalk and soapstones
Tools are made using metal because when a force is exerted on the metal, the positive ion layer can move down on top of another layer without breaking. For ionic compounds, if a strong force were to be exerted it would shatter the entire thing. Also metals are malleable, ductile and they have high melting points. This is good because you don't want the tools to be melting when a small amount of friction occurs. Metals are also insoluble in water.
Metals are often chosen to make tools because they are strong, durable, and have good conductivity and ductility properties. These characteristics make metals suitable for withstanding the wear and tear of tool usage and allow them to be easily shaped into different tool designs. Additionally, metals can help provide stability and precision in tool performance.
Aluminium Zinc Chromium Cobalt Copper
Tools = wood + Metals
Rocks are useful because without them, we wouldn't exist. They make tools, games, ect. (I'm sure you can find a more in-def answer, I just answered this because it HAD no answer. Feel free to edit.)
