Question

If markings on a thermometer are wiped out ,how dowe create new markings??

Answer 1

• We can create new markings on a thermometer by using a simple technique.

• First, we should keep the thermometer in ice glass for two minutes.

• Mark the mercury levels. After melting the ice mercury levels are the same.

• That means the temperature is constant so marked it with 0°C

• We should boil the water then it would be converted into steam.

• Now the mercury levels are raised and reached a certain point.

• We can mark the level at this point as 100°C.

• So we need to fix the melting point is 0° C and the boiling point is 100°C.

• This is the way we can create new markings on a thermometer.

Answer 2

we can create new markings on thermometer by using a simple technique :-

Explanation:

=> first,we should keep the thermometer in ice glass.

=> mark the mercury levels. after melting the ice mercury levels are same.

=> that means the temperature is constant so mark it with 0°C.

=> we should boil the water then it would be converted into steam.

=> now the mercury levels are raised and reached a certain point.

=> we can mark the level at this point as 100°C.

=> so we need to fix the melting point as 0°C and the boiling point is 100°C.

=> this is the way we can create new markings on a thermometer.
