insens350 [35]

Answer: Metamorphic rocks are formed from other rocks that are changed because of heat or pressure. They are not made from molten rock. rocks that do melt form igneous rocks instead. Earth movements can cause rocks to be deeply buried or squeezed. As a result, the rocks are heated and put under great pressure.

The half life of Carbon-14 is 5730 years. You measure a rock sample and find that it has trace amounts of Carbon-14. 1/2408 rema
hram777 [196]

Given :

The half life of Carbon-14 , t_{0.5}=5730 .

Trace amounts of Carbon-14 1/2408 remains.

To Find :

How old is the rock .

Solution :

Let , initial concentration of Carbon-14 is C .

Quantity remains , \dfrac{C}{2408} .

Rate constant is :

k=\dfrac{0.693}{t_{0.5}}\\\\k=\dfrac{0.693}{5730}\\\\k=1.2\times 10^{-4}\ years^{-1}

By first order equation :

kt=-ln(\dfrac{[A_t]}{[A_o]})\\\\t=-\dfrac{ln(\dfrac{[A_t]}{[A_o]})}{k}\\\\t=-\dfrac{ln(\dfrac{[A_o]}{[A_o]\times 2408})}{1.2\times 10^{-4}}\ years\\\\t=-\dfrac{ln(\dfrac{1}{2408})}{1.2\times 10^{-4}}\ years\\\\t=64887.9\ years

Therefore , the rock is 64887.9 years old .

Hence , this is the required solution .
