Helium is not used to fill gas balloons. True/False

Text Solution

AI Generated Solution

The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Statement**: The statement claims that "Helium is not used to fill gas balloons." We need to determine if this statement is true or false. 2. **Properties of Helium**: Helium is a noble gas that is lighter than air. Its atomic mass is about 4 g/mol, making it suitable for filling balloons as it provides lift. 3. **Comparison with Hydrogen**: While hydrogen is lighter than helium and provides more lift, it is highly flammable and poses safety risks. This makes helium a safer alternative for filling balloons. 4. **Common Usage**: Helium is widely used in party balloons, scientific balloons, and other applications where a non-flammable gas is required. 5. **Conclusion**: Since helium is indeed used to fill gas balloons due to its non-flammable nature and lighter-than-air properties, the statement that "Helium is not used to fill gas balloons" is false. **Final Answer**: False ---
