For the construction of a thermometer one of the essential requirements is a thermometric substance which
- A. remains liauid over the entire range of temperatures to be measured
- B. has a property that varies linearly with temperature
- C. has a property that varies with temperature
- D. obey Boyle's law
Step-by-step solution
For a thermometer to function, the thermometric substance must have a property (e.g., volume, pressure, resistance) that changes detectably with temperature, allowing temperature to be inferred from that change. While linearity (B) is desirable for easy calibration, it is not essential. Remaining liquid (A) or obeying Boyle's law (D) are specific and not universally required.
