Question

Calculate the annual range of temperature.
A)11
B)13
C)15
D)26

Answer 1

Hint: 1)The annual range is defined as the difference between the mean temperatures of the hottest and coldest months.
2)It is determined by subtracting the monthly mean minimum temperature from the monthly mean maximum temperature each year.

Complete answer:
The annual range is defined as the difference between the hottest and coldest months, with mean monthly temperatures being used in each case.
The difference between the average maximum temperature in January and the minimum temperature, and the corresponding average temperature in July.
January being coldest month with mean temperature =11’ C
July being the hottest month with mean temperature = 26’C.

Lets see the options :
A)11 : the annual range of temperature is 15 not 11 after calculating it thus this option is wrong
B)13 : the annual range of temperature is 15 after calculating it thus this option is wrong .
C)15 : the annual range of temperature is 15 after calculating it thus this option is correct.
D)26 : the annual range of temperature is 15 not 26 after calculating it thus this option is wrong

Hence, the correct answer is option (C)

Note: 1)NASA data shows that the global average temperature in 2019 was 1.8 degrees F (0.98 degrees C) warmer than the average temperature in the 20th century. 3 In fact, all the five warmest years have occurred since 2015 in the 1880-2019 record.

2)The three mechanisms of moving heat from a material at a higher temperature to one at a lower temperature are conduction (occurs in solids), convection (occurs in liquids) and radiation (takes place through space).
