Question

If markings on thermometer are wiped out then how do we create new markings

Answer 1

Answer:

In the case that markings on a thermometer are wiped, following steps should be followed to create new markings,

Step 1:

Place the thermometer in a glass of ice, for approximately 2 minutes.

Step 2: Look at the mercury levels and mark them because when the ice melts those levels will remain same.

Step 3: In the case that those mercury levels are same, temperature will be constant. If a temperature is constant, it should be labelled 0 degree Celsius.

Once this extreme point has been covered, now will be the point of covering the other extreme level.

Step 4: Boil water until steam is formed.

Step 5: Observe the raised mercury levels and label it 100 degree Celsius.
