Answer:
N₂ gas at 50 °C.
Explanation:
- From the postulates of the kinetic theory of gases; <em>all gases at a given temperature have the same average kinetic energy</em>.
- The average kinetic energy of gases can be calculated from the relation: K =
T.
Where, K is the average kinetic energy (measured in Joule),
R is the general gas constant (R = 8.314 J/mol.K)
NA is Avogadros number (6.023 x 10²³ atoms/mol)
T is the temperature (measured in Kelvin).
- It is clear from the relation that K depends only on the temperature.
- So, N₂ gas at 50 °C has the highest average kinetic energy since it is at the higher temperature than other gases.
Due to the fact nitrogen diffuses faster than chlorine nitrogen has insures called co2 which implodes the chlorine which leads to nitrogen having a faster diffusion

C
Explanation:
The idea here is that the problem is providing you with the amount of heat needed to raise the temperature of a given sample of water from an initial temperature to its boiling point, i.e. to 100
Answer:
Take E(alpha particle energy) = 5.5 MeV (5.5x106x1.6x10-19)
If the charge on the lead nucleus is +82e(atomic number of lead is 82) = +82x1.6x10-19 C and the charge on the alpha particle is +2e = 2x1.6x10-19 C
Using dc = (1/4πεo)qQ/Eα we have
dc = [9x10^9x(2x1.6x10-19x82x1.6x10-19)]/5.5x10-13 = 6.67x10^-13m. = 6.67 x 10^-13 x 10^15 = 6.67 x 10^2fm
Note: 1meter = 10^15fentometer
Explanation:
This is well inside the atom but some eight nuclear diameters from the centre of the lead nucleus.
