A mercury-in-glass thermometer reads -20°at ice point, as 100°at steam point. calculate the celsus temperature corresponding it 70°on the thermometer
-75°c
To calculate the Celsius temperature corresponding to 70° on the thermometer, we need to determine the temperature equivalent for each mark on the thermometer.
Given that the thermometer reads -20° at the ice point and 100° at the steam point, we have a range of 120° (100° - (-20°)) in which the thermometer operates.
We can calculate the temperature equivalent for each mark on the thermometer using the formula:
Temperature Equivalent = (Temperature Range / Total Thermometer Scale) × Mark on the Thermometer
In this case, the temperature range is 120° and the total thermometer scale is the number of divisions on the thermometer, which we don't have in the question. Let's assume it is divided into 100 equal divisions.
Based on this assumption, we can calculate the temperature equivalent for each division:
Temperature Equivalent = (120° / 100 divisions) × Mark on the Thermometer
For 70° on the thermometer, substitute the value into the formula:
Temperature Equivalent = (120° / 100 divisions) × 70
Temperature Equivalent = 84° Celsius
Therefore, the Celsius temperature corresponding to 70° on the thermometer is 84° Celsius.
