In this class we are going to learn on Recording and Calculating temperature and also the instruments used to measure temperature
Answer Text: Recording and Calculating Weather Conditions Temperature -Degree of hotness of an object or a place. It’s measured using 3 types of thermometers namely: 1. Maximum thermometer 2. Minimum thermometer 3. Six’s thermometer Maximum ThermometerIt’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. Minimum Thermometer 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. Calculating Temperature 1. Diurnal/daily Temperature range -Difference between the maximum and minimum temperature for any one day. 2. Mean Daily Temperature - Average of the maximum and the minimum daily temperatures.3. Mean Monthly temperature - Sum of mean daily temperatures in a month divided by the number of days in that month. 4. Mean Monthly minimum Temperature - Sum of daily minimum temperatures divided by the number of days in that month. 5. Mean Monthly Maximum Temperature- Sum of daily maximum temperatures divided by the number of days in that month. 6. Mean Annual Temperature - Sum of mean monthly temperatures divided by 12. 7. Mean Annual Temperature Range - Difference between the highest and the lowest mean monthly temperatures in a year.8. ◦k=◦c+273 9. ◦F=(◦c×1.8)+32 derive the rest from the formulas.
