🔍 Key Concepts

• Battery electrolyte is a corrosive liquid (often acid) inside certain batteries • Different thermometers are designed for different temperature ranges and chemical environments • Some instruments are meant for contact with liquids, others for high-temperature surfaces or electrical measurements

💭 Think About

• Which device is safe and practical to insert into a corrosive liquid without being damaged or posing a breakage hazard? • Which option is commonly used in maintenance work for getting quick, accurate readings in moderate temperature ranges, not extreme high temperatures? • Which of these instruments is specifically designed to measure temperature directly, rather than electrical properties like voltage or resistance?

✅ Before You Answer

• Eliminate any device mainly used for very high temperatures (like furnaces or exhaust systems) • Eliminate any device whose primary purpose is to measure electrical values rather than temperature • Think about which device is commonly used in marine and industrial settings for safe, accurate liquid temperature measurements
