Question 1 of 27070

Q

A material flashed by the application of heat after the tube is evacuated that absorbs any gases remaining inside the tube:

🔍 Key Concepts

• Vacuum tubes and the purpose of removing residual gas • The role of a special material or component added inside a tube after evacuation • Difference between elements that control electron flow and those that clean up remaining gas

💭 Think About

• Which tube element’s job is specifically to deal with leftover gas molecules after the air has been pumped out? • Which options (space charge, getter, collector, emitter) are mainly about handling electrons, and which one is about handling gas? • Think about what is heated after evacuation: is it a normal electrode, or a separate material whose vapors react with gas?

✅ Before You Answer

• Identify which choice refers to a reactive material rather than an electrical electrode. • Eliminate options that are primarily involved in electron emission or collection. • Recall that the correct term is used for a substance that absorbs residual gases in evacuated tubes.
