Chapter 12, Problem 109A

Interpretation Introduction

Interpretation:

An oral presentation must be prepared about plasma.

Concept introduction:

Plasma is a state which is present at very high temperature.

Answer to Problem 109A

Apart from three states( solid, liquid and gas) another state is plasma state.

In the core of the stars including sun the matter (different metals) are in plasma state.

Explanation of Solution

In this state there are gaseous ions which are electrically charged. So these ions are highly electrically conductive. These charged ions and free electrons which are removed from neutral gaseous atoms are influenced by long range electromagnetic field. Thus plasma state is more sensitive than neutral gaseous atom towards electromagnetic field.

Conclusion

Plasma state is the fourth physical state of matter. It contains charged gaseous ions.
