Answer:
Thus the time taken is calculated as 387.69 years
Solution:
As per the question:
Half life of 
= 28.5 yrs
Now,
To calculate the time, t in which the 99.99% of the release in the reactor:
By using the formula:
where
N = No. of nuclei left after time t
= No. of nuclei initially started with
(Since, 100% - 99.99% = 0.01%)
Thus
Taking log on both the sides:
t = 387.69 yrs
The transition from gas to liquid is called condensation. An example would be water droplets forming on an ice cold glass placed in room temperature.
Incompressible. Compressibility is determine by the amount of space between particles in each state.
