A. All natural radiation is at a level low enough to be safe
<span>Even though the Sun has a greater mass than Earth, the Moon orbits Earth because it's closer to the Earth than to the Sun. Because of this proximity between the Earth and the Moon, the Earth has a stronger gravitational pull than the Sun does. Furthermore, the Earth's mass is 81 times that of the Moon, and so at this proximity, it is more than able to overpower what pull the Sun exerts on the Moon.</span>
Answer:
<em>Option D: It iwill actually warm the room</em>
<em></em>
Explanation:
<u>To complete your given question the available options are:</u>
A. It will cool the room very effectively
B. It will cool the room, but inefficiently
C. It will not change anything
D. It will actually warm the room.
This is a fun and somewhat tricky case. So, let us first understand a few principles in order to answer our question. To begin with<u><em>, the basic operating principle of the fridge is to take the hot air from the surrounding environment and cool it to the desired temperature in order to sustain all products inside the fridge</em></u>. It can also be thought as 'transferring' heat from the interior (i.e. inside the fridge) to the exterior (i.e. outside the fridge and into the surrounding).<em> In fact if you check the back of a fridge during operation, you will noticed a much higher temperature in that area. Which is due to the heat removed by the 'fridge operation system' in order to cool that interior air.</em> Therefore, this heat must transfer somewhere else, which typically ends up on the little fan located on the back of the fridge. We can also think of it in terms of the 2nd Law of Thermodynamics, which essentially tells us that the system (in this case the fridge and its surrounding)<em> MUST reach an Equillibrium.</em>
Therefore, when you do open the door of the fridge, you might initially (and for an instant almost) feel this 'cool' air coming out; thinking the surrounding air should soon cool down as well. But, due to our discussion above along with the principles of the 2nd Law of Thermodynamics, and considering the fridge operation over time,<em><u> the more cool air the fridge looses, the more the fridge system works to cool the air, thus the more the fans of the fridge work, which results to increasing heat getting 'dumped' by the fridge system and thus to the surrounding. </u></em>
<em></em>
<em>Consequently when you open the fridge door you will actually warm the room. (i.e. Option D). </em>
Removing an electron from a neutral atom will result in an atom that is positive.
Okay, let me reword this. Heat flows to areas that are cool, however, once the heated area begins to cool, the other area begins to warm up. Then there comes a point when there is no energy being transmitted into the two areas. When that happens the two areas obtain/are at the same temperature.
For example, you let the warm are escape your kitchen and go into the cold garage. You leave the kitchen door open and the heat continues to flow into the cold garage. After a while you will begin to notice that the kitchen feels noticeably cooler and the garage feels somewhat warmer. Then you wait a while longer and realize that both of the rooms feel like they are at the same temperature. They have then reached equilibrium.
