Since each serves a different purpose, theories cannot become
laws. Explaining how or why a natural phenomenon occurs is what the set of ideas
called theories do. On the other hand, mathematical relationships that
describes what happens are what is done by laws.
Let me show an example that illustrates the points.
Describing what happens in the natural world are done by the mathematical
formulas called the Gas Laws. In this example, it would show that by using the
Gas Laws, I will be able to predict with great accuracy the pressure if I
double the temperature of a sealed gas. This idea is a law since the
relationship is mathematical and it tells us what will happen.
<span>On the other hand, in order to explain why gases behave like
the way they do, we must use the kinetic molecular theory.</span>
The total mass of the mixture would not change.
Think about it as a mix of marbles. Suppose you have a group of 10 marbles. 5 marbles are red, and 5 marbles are blue. If you separate the marbles into 2 different groups by color, you still have 10 marbles in total, but they are separated and no longer a mixture of colors.
The mechanical energy changes into the electrical energy.
The fact is your rooftop is covered with dust particles from meteorites. Outerspace is full of debris. Every day, thousands of meteorites invade our home but thanks to atmosphere for keeping us safe from them :D
When these meteorites enter our atmosphere, they experience resistance to the particles present in our atmosphere. As a result they catch fire(and eventually melts) and lose all their energy before falling on the surface. This happens with very small sized meteorites but when bigger ones enter, they surely hit the surface because they are difficult to melt.
Thanks to Jupiter for saving us from asteroids. Bigger ones rarely enters our atmosphere because of Jupiter's gravitational pull. It lures all the debris towards itself (:
Hey there!
You cannot cut through steel with a plastic knife. As fun as it sounds, it is <u>not </u>a good idea to try, and 99.9% of the time it would not work.
Hope this helps!
