Answer:
Is the equation for Ec=1/2 m(Dv)^2 where Dv is the difference between the angular speed & the areolar speed?
Answer:
1. K.E = 11.2239 kJ ≈ 11.224 kJ
2. 
3. 
Solution:
Now, the kinetic energy of an ideal gas per mole is given by:
K.E = 
where
m = no. of moles = 3
R = Rydberg's constant = 8.314 J/mol.K
Temperature, T = 300 K
Therefore,
K.E = 
K.E = 11223.9 J = 11.2239 kJ ≈ 11.224 kJ
Now,
The heat capacity at constant volume is:


Now,
Required heat transfer to raise the temperature by
is:



More mass will in turn create more force in a collision.
The number of marbles in a collision will affect the outcome because they could bounce off each other and what not.
