Final answer:
A gas does not conduct electricity, unlike a plasma which contains charged particles and conducts electricity.
Therefore, the correct answer is option 1) does not conduct electricity
Step-by-step explanation:
Unlike a plasma, a gas does not conduct electricity. Both gases and plasmas are states of matter with no definite shape or specific volume, as their atoms or charged particles are widely separated and move to fill their containers. However, plasmas contain a large number of electrically charged particles, making them capable of conducting electricity and being affected by magnetic fields.
Gases typically consist of uncharged atoms or molecules, therefore lacking the free electrons and ions found in plasmas that contribute to electrical conductivity.
Unlike a plasma, a gas lacks a definite shape, making option 2) the correct choice. Gases are characterized by their ability to fill the entire container they occupy, adapting to its shape. While both gases and plasmas do not have a definite shape, plasmas, unlike gases, can conduct electricity effectively.
Thus, the key distinction lies in the electrical conductivity, and gas is less conductive compared to a plasm
Therefore, the correct answer is option 1) does not conduct electricity
