General Science (Easy) Chemistry

Mercury is used in the thermometer because

1) it has relatively uniform expansion

2) it is opaque and so is easily visible in glass

3) it does not wet or stick to the glass

it remains liquid at ordinary temperatures

Which of these statements is/are correct?

1 only

2 only

Both 1 and 2

All

- Statement 1: Mercury has relatively uniform expansion, which ensures accurate temperature readings over a range of temperatures.

- Statement 2: Mercury is opaque, making it easily visible in glass thermometers, which helps in reading the temperature.

- Statement 3: It does not wet or stick to glass, which allows for easy movement of the liquid in the thermometer for precise readings.

- Statement 4: Mercury remains liquid at ordinary temperatures, making it suitable for a wide range of temperature measurements.

- Option 4: All statements are correct as they highlight the reasons why mercury is used in thermometers.

Correct Answer: Option 4 - All
