🔍 Key Concepts

• Behavior of gases in indicator tubes or discharge tubes • Typical visual indications (such as glow or lack of glow) used to detect gas presence • Difference between color of light and simple presence/absence of light

💭 Think About

• Think about what changes in a tube when gas is present versus when it is absent: does the color change, or does the visibility of any glow change? • If you were designing a simple indicator to show gas presence, would you rely on a specific color or on whether any glow appears at all? • Consider which option(s) would still be valid if different types of gases or mixtures were used in the tube.

✅ Before You Answer

• Check whether the question asks about a specific color or about presence/absence of a glow • Verify which choice (if any) would remain correct for any gas type, not just one particular gas • Confirm that the correct choice should be consistent with basic electrical discharge in gas: either there is a glow, or there is not
