Chapter 6, Problem 126AP

Interpretation Introduction

Interpretation:

The temperature of the corona, by studying the emission lines of ions of certain elements, is to be determined.

Concept introduction:

An atom is made up of the nucleus (positively charged) and electrons (negatively charged) revolving around the nucleus in the orbits called energy levels or energy states.

If an electron moves from one energy level or energy state to another energy state, it is termed as the transition of electron. Energy is either lost or absorbed during the transition of electron.

The average kinetic energy of the gas is given as

$\Delta E=\frac{3}{2}RT$

Here, R is gas constant and T is temperature.

The relationship between kilojoules and joules can be expressed as $\text{1kJ}\text{}\text{}\text{=}\text{1000J}$.

For conversion of kilojoules to joules, the conversion factor is $\frac{1000\text{ J}}{1\text{ kJ}}$.
