Q

What characteristic does a chemical additive to LPG give it?

🔍 Key Concepts

• Liquefied Petroleum Gas (LPG) is naturally hard for humans to detect without assistance • The purpose of adding chemicals (like mercaptans) to some gases • Which property of a gas most directly helps people notice a leak with their own senses

💭 Think About

• If LPG leaks into a space, which sense would you realistically rely on first to notice it? Sight, smell, touch, or hearing? • Do we usually change a gas’s physical behavior (like pressure or density), or do we change how easy it is for humans to detect it? • Think about common household fuel gases—what is added so people can recognize a leak quickly and take action?

✅ Before You Answer

• Ask: Which option is specifically about detection by humans, not changing how the gas behaves physically in a system? • Eliminate choices that mainly affect system design (piping strength, tank rating) rather than human safety sensing. • Confirm which characteristic is commonly altered in domestic gas supplies so leaks can be recognized immediately.
