Chapter 20, Problem 34E

(a)

Interpretation Introduction

Interpretation:

The reason that ${}^{40}Ar{/}^{40}K$ ratios are used to date material rather than ${}^{40}Ca{/}^{40}K$ ratios is to be determined.

Concept Introduction:

The decaying of particle can be called as spontaneous process in which one unstable subatomic particle transforms into multiple other particles. The particles which are created by this process will have less mass in comparison of the original particle.

(b)

Interpretation Introduction

Interpretation:

The assumptions which are taking into consideration for using this technique are to be determined.

Concept Introduction:

The decaying of particle can be called as spontaneous process in which one unstable subatomic particle transforms into multiple other particles. The particles which are created by this process will have less mass in comparison of the original particle.

(c)

Interpretation Introduction

Interpretation:

The age of rock is to be calculated.

Concept Introduction:

The decaying of particle can be called as spontaneous process in which one unstable subatomic particle transforms into multiple other particles. The particles which are created by this process will have less mass in comparison to the original particle.

(d)

Interpretation Introduction

Interpretation:

The method which is used to measure the age of rock compared with the actual age if some ${}^{40}Ar$ has escaped from the sample is to be determined.

Concept Introduction:

The decaying of particle can be called as spontaneous process in which one unstable subatomic particle transforms into multiple other particles. The particles which are created by this process will have less mass in comparison to the original particle.
