This is the visible light spectrum is the only portion that the human eye can detect or "see".
When the engine's <em>operating speed increases</em> the temperature of the engine will also increase.
Given:
Automobile engines without a cooling system.
To find:
The affect on the temperature of the engine as its operating speed increases.
Solution:
The speed of the operating engine increases.
- As we know that kinetic energy of the object and motion of the object is directly proportional<em> </em>to each other.
<em>Velocity </em><em>of object </em><em>∝ Kinetic energy </em><em>of object...[i]</em>
- When the<em> kinetic energy</em> of the object increases the kinetic energy of the particles of the object also increases.
- And <em>kinetic energy</em> of the particles is directly linked to the <em>temperature </em>of the object.
<em>Kinetic energy</em><em> ∝ </em><em>Temperature </em><em>of object</em>...[ii]
From [i] and [ii] :
<em>Velocity </em><em>of object ∝ </em><em>Temperature </em><em>of an object</em>
- When the engine's operating speed increases it will increase the kinetic energy of its particles and with that increase, the increase in the temperature of the engine will be <em>observed</em>.
So, from this, we can conclude when the engine's operating speed increases the temperature of the engine will also increase.

Answer:
The electrons in the outermost electron shell are responsible for forming chemical bonds. These electrons are also known as valence electrons. Chemical bonds are formed when the outermost electron shells are not completely filled and atom needs more (or less) electrons to completely fill the outermost shell.
