V = displacement /time
= 3/3 = 1km/hr
Answer:
moves molecules
Explanation:
I did this one yesterday! Active transport moves low to high concentration and passive does the opposite so C and D are not an option. Active transport requires energy and Passive Transport does not so it has to be A.!
4157 J work is done by the gas , If 2 moles of helium undergo a temperature increase of 100 K at constant pressure.
<h3>What are Noble Gases ?</h3>
The noble gases are helium, argon, krypton, xenon, and radon, in order of their mass.
They are called noble gases because they are so majestic that they do not react with anything in general.
The work done can be calculated by the formula
Q=n Cp ΔT
Cp= ( 1+ f/2)R
R= 8.3144598 J. mol-1.
Cp = (1+3/2) * 8.314
Cp = 5*8.314/2
Q= 2 * 5 *8.314 *100/2
Q = 4157 J
Therefore 4157 J work is done by the gas , If 2 moles of helium undergo a temperature increase of 100 K at constant pressure.
