Question

The maximum and minimum temperature of a day is 48⁰c and 32⁰c. Calculate the mean daily temperature.
A. 39⁰C
B. 40⁰C
C. 41⁰C
D. 42⁰C

Answer 1

Hint: The temperature is defined as the degree of hotness or coldness of an object. It varies from place to place depending on the climatic condition of the place.

Complete Answer: The average temperature of the air as demonstrated by an appropriately exposed thermometer during a given duration , generally a day, a month, or a year. The mean temperature is generally estimated for each month and for the year.
It is the average temperature in each interval of 24 hours. It is calculated at 1.5 meters above ground level.Mean daily temperature can be calculated by finding out the average of maximum and minimum temperature of a day.

Mean daily temperature = 48 +32/ 2
​
Mean daily temperature = 40°C

So, the mean daily temperature is 40°C.

Note:
- The temperature of places fluctuate depending on the altitude and latitudinal extents. Generally, when one raises up in altitude, the temperature decreases at a certain rate. This is called the normal lapse rate.
- Sometimes, there is an alteration in this property and the temperature starts to increase after a certain height instead of decreasing. This is called inversion of temperature.
