select from this list the one metal or alloy that is best suited for each of the following applications, and cite at least one r
Brut [27]

<em>List of metal or alloy that is best-suited include :</em>

<em>1) Block of an </em><em>internal combustion </em><em>engine is made of grey cast </em><em>iron </em><em>because it is </em><em>ductile </em><em>and hard enough to bear the loads.</em>

<em>2) Steam heat exchanger is made up of </em><em>stainless steel </em><em>material as it has high resistance to </em><em>corrosion </em><em>and has the capacity to bear high-</em><em>temperature </em><em>differences.</em>

<em>3) For jet engine </em><em>turbofan blades</em><em>, titanium alloys are being used because they can able to bear high pressure and high energy loads.</em>

<em>4) Tool </em><em>steel </em><em>is used to make drill bit material as it has high </em><em>tensile </em><em>and point strength.</em>

<em>5) </em><em>Aluminum alloys </em><em>are used for </em><em>cryogenic </em><em>applications as it is the best suited for work at low </em><em>temperatures</em><em>.</em>

<em>6) </em><em>Magnesium </em><em>is used for </em><em>pyrotechnics </em><em>as it gives works on the effect of heat, </em><em>light</em><em>, and gas. </em>

Alloy, a metallic substance composed of two or more elements, as both a compound or a solution. The components of alloys are ordinarily themselves metals, though carbon, a nonmetal, is an essential constituent of metal.

Alloys, in trendy, are more potent and harder, less malleable, much less ductile, and greater corrosion-resistant than the alloy's predominant metallic.

An alloy is created with the aid of mixing metallic with another issue, both any other metal or a nonmetal substance. Metallic alloys are commonly made by means of melting the substances, mixing them collectively, after which letting them cool to room temperature, ensuing in a strong material.

When studying atoms, scientists can ignore the
vekshin1

When studying atoms, scientists can ignore <u>the Gravitational</u> force between charged particles that make up  the atoms because it is many millions of times smaller than other forces in the atom.

Explanation:

Scientists can ignore the gravitational force because the gravitational force is considered to be negligible as compared to the other forces due to its smaller value.We all know that the gravitational force is directly proportional to the mass of an object which  result in  a small force value.When the value of this small force is compared to the value of the electrical force between protons and electrons in atoms the we can say that the electrical force is million times stronger than the gravitational force

Thus we can say that scientists can ignore <u>the Gravitational</u> force between charged particles that make up  the atoms because it is many millions of times smaller than other forces in the atom.

Who discovered atomic structure​
Yuliya22 [10]
John Dalton

Although the concept of the atom dates back to the ideas of Democritus, the English meteorologist and chemist John Dalton formulated the first modern description of it as the fundamental building block of chemical structures.
