The word “conservation” refers to an amount that is unchanged. The total amount of energy in the universe remains the same.
Answer:
1.71atm
Explanation:
The following were obtained from the question:
V1 (initial volume) = 6L
P1 (initial pressure) = 1atm
V2 (final volume) = 3.5L
P2 (final pressure) =?
Using the Boyle's law equation:
P1V1 = P2V2, the final pressure can be obtained as follow:
P1V1 = P2V2
1 x 6 = P2 x 3.5
Divide both side by 3.5
P2 = 6/3.5
P2 = 1.71atm
The final i.e the new pressure inside the piston is 1.71atm
We see that in 1 rock, there are 31 atoms of Argon and 1
atom of Potassium so the relative concentration of Potassium is:
1 / 32
or can be written as:
1 / 2^5
So this means that 5 half-lives have passed.
So the years are:
<span>years passed = 5 * 1.25 billion years = 6.25 billion years</span>
