An isotope of an element contains the same number of protons as the original element however, the number of neutrons depends on the different isotopes of the element.
<span>C) Pressure will compress a gas, reducing its volume and giving it a greater density and concentration of particles.
Let's look at the available choices and determine why or why not they're correct.
A) Pressure will expand a gas, enlarging its volume and reducing its density and concentration of particles.
* What? So increasing the pressure on a gas will make it take up a larger volume? That definitely doesn't match the world I live in. I hope that's true for you as well. Wrong choice.
B) Pressure will magnify a gas, developing its volume and multiplying its density and concentration of particles.
* Lots of interesting sounding words, but they're mostly used in a nonsense fashion. Useful if you're easily fooled by technobabble, but it's another wrong answer.
C) Pressure will compress a gas, reducing its volume and giving it a greater density and concentration of particles.
* OK. Increasing the pressure will compress a gas. So it has a smaller volume. And since it still has the same mass, the density will become greater. And the particles closer together. Everything here matches reality. Good choice.
D) Pressure will accelerate a gas, extending its volume and allowing a smaller density and concentration of particles.
* Most technobabble. Why would the gas be accelerated? No reason that I know of. Wrong choice.</span>
Answer:
Yeah it's ok I think. Also, I can't see the answer you gave so maybe updating the question would be nice.
Answer:
1) F1
Explanation:
As the air resistant force depends on the speed of object and its orientation as it falls, it does not depend on the mass of the object. Therefore, air resistant force on 1 coffee filter is the same as the air resistant force on 3 coffee filters.
