The arrow that will represent the phase change that involves the same amount of energy as arrow 1 will be arrow 4.
<h3>Phase change</h3>
Arrow 1 represents a phase change from liquid to gas while arrow 4 represents a phase change from gas to liquid.
In other words, arrow 1 and arrow 4 are direct opposites of one another,
This means that if X amount of energy is required for arrow 1, the same amount of energy will be needed for arrow 4 but in the reverse direction.

The International Date Line passes through the mid-Pacific Ocean and roughly follows a 180 degrees longitude north-south
line on the Earth. It is located halfway round the world from the prime meridian—the zero degrees longitude established in Greenwich
<span>A flashlight is an electric-powered light source; the light source is a light bulb or an LED. The electrical energy is converted into visible light. Flashlights can be hand-held or mounted to a platform. Light from a lighting, on the other hand, is formed by exciting electrons to a higher state. </span>
