Answer:
the volume will increase
Explanation:
The kinetic energy of gas molecules depend upon the temperature . If temperature is increased , the molecules will move faster . When temperature is decreased , they move slower .
Hence when more molecules are added to a gas without changing its temperature , the velocity of gas molecules will remain unchanged .
Since pressure is also constant , it is volume which will be increased .
It can be explained from universal gas formula as follows
PV = nRT
P , R and T is constant ,
V ∝ n
Volume is proportional to n which depends upon number of molecules .
So volume will increase if number of molecules increases .
Answer:
7L
Explanation:
Divide 101 by 10.1(kPa) and you get 10.
10 x .7 = 7
Answer:
if you add or subtract a neutron from an atom it will become a new isotopes of the same element
N the nucleus, there are protons and neutrons. That's two parts.
<span>Outside the nucleus, there are electrons. That's a total of three parts and that is all that chemists discuss. Theoretical physicists talk about other sub nuclear "parts", but if you include them, the number goes way over 5. </span>
<span>The "shells", "sub-shells", "orbits", "orbitals", "probabilities" and the like are not physical parts, but only descriptions of energy</span>
All the answers are on the actual periodic table. You should never be told to remember it so I think this is a recourse you are allowed to look at whilst doing your homework lol :) all the answers are written on it hope it helps
