What is the range of Laboratory thermometer?

–10°C to 110°C

The correct answer is option 3. –10°C to 110°C.

A laboratory thermometer is designed to measure temperatures within a specific range suitable for laboratory applications. The range of -10°C to 110°C or 0°C to 100°C is commonly found in laboratory thermometers. Here's an explanation of the range:

1. Negative Temperatures (-10°C):  This part of the range allows the thermometer to measure temperatures below freezing, useful for applications involving substances or environments that experience cold temperatures.

2. Room Temperature (0°C to 25°C): The range includes temperatures commonly found in indoor laboratory settings, ensuring that it can measure standard room temperatures.

3. Moderate Temperatures (25°C to 50°C):  This section covers a range of moderate temperatures often encountered in various laboratory processes.

4. High Temperatures (50°C to 100°C): This part of the range allows the thermometer to measure elevated temperatures, suitable for applications involving heat sources or reactions that generate significant heat.

5. Extended Range (100°C to 110°C): This portion covers temperatures slightly above the boiling point of water at standard atmospheric pressure, providing some extra capacity for measurements in certain situations.

Laboratory thermometers are commonly used in scientific experiments, quality control processes, and various other applications where precise temperature measurements are required within the specified range. It's important to choose a thermometer with an appropriate range for the specific needs of the laboratory.
