🔍 Key Concepts

• mechanical carbon dioxide recorder – what physical property can it actually move or measure? • Difference between air and flue gas when CO₂ is present (think density / weight vs color or temperature) • How older, non-electronic gas analyzers typically detected gas concentration

💭 Think About

• Which of these choices represents a property that can create a mechanical force or movement in a device (e.g., float, bell, diaphragm)? • Would a simple mechanical instrument be able to reliably sense color, soot, or temperature alone and directly convert that into a mechanical recording? • When CO₂ is added to air, which property of the gas mixture changes in a predictable way that a mechanical sensor could use?

✅ Before You Answer

• Identify which option describes a weight/density-related property rather than an appearance or heat property. • Ask yourself: which property of the flue gas would change directly and measurably with CO₂ concentration in a purely mechanical device? • Eliminate options that would normally require optical or electronic temperature sensing rather than simple mechanical means.
