Degree of hotness of an object or a place.
It’s measured using 3 types of thermometers namely:
- Maximum thermometer
- Minimum thermometer
- Six’s thermometer
It’s used to measure the highest temperature reached in a day.
It uses mercury.
How It’s Used/Works
- Temperature rises causing mercury to expand.
- Mercury pushes the index up.
- When temperature falls mercury contracts.
- The maximum temperature is read from the scale at the lower end of the index.
- Thermometer is reset by shaking it to force mercury back into the bulb.
It’s used to record the lowest temperature reached in a day.
It uses alcohol.
How it’s Used/Works
- Temperature falls causing alcohol to contract.
- Alcohol pulls the index down.
- When temperature rises alcohol expands and rises in the tube.
- The index remains where it was pulled.
- Minimum temperature reading is obtained from the scale at the lower end of the index.
- Diurnal/daily Temperature range
-Difference between the maximum and minimum temperature for any one day.
- Mean Daily Temperature
– Average of the maximum and the minimum daily temperatures.
- Mean Monthly temperature
– Sum of mean daily temperatures in a month divided by the number of days in that month.
- Mean Monthly minimum Temperature
– Sum of daily minimum temperatures divided by the number of days in that month.
- Mean Monthly Maximum Temperature
– Sum of daily maximum temperatures divided by the number of days in that month.
- Mean Annual Temperature
– Sum of mean monthly temperatures divided by 12.
- Mean Annual Temperature Range
– Difference between the highest and the lowest mean monthly temperatures in a year.
- ◦F=(◦c×1.8)+32 derive the rest from the formulas.
