Mercury thermometer can be used to measure the temperature upto ____________ °C?
Correct answer: C. 350
- A. 100
- B. 250
- C. 350
- D. 750
Explanation
Mercury boils at about 357°C, so a mercury thermometer is commonly used up to approximately 350°C. Beyond this limit, vapour pressure and loss of mercury make it unsuitable.
