Question

Q38.how much is the increase in temperature from 1880 to 2010?

Answer 1

Answer:

Since the 1880, the average global temperature approximately increased with the average rate of 0.07 degrees Celsius (0.13 degrees Fahrenheit) every 10 years.

Explanation:

since 1880 the world was on the initial stage of development. these development led to the increase in temperature. the reasons for the increase in global temperature were:

• increase in population
• increase in industrial output

they actively contributed to the increase in many harmful gases which trapped heat in the planet which in turn increased the level of average global temperature.

Answer 2

Increase in temperature is 130 K .

Given :

Initial temperature , $T_i=1880\ K$  

Final temperature , $T_f=2010\ K$

( Here units are not given so we take the S.I unit i.e Kelvin ( K ) )

Now , we need to find the increase in temperature .

We know , increase in temperature is given by the difference between final and initial temperature .

Therefore ,

$\Delta T=T_f-T_i\\\\\Delta T=2010-1880\\\\\Delta T=130\ K$

Therefore , increase in temperature is 130 K .

Hence , this is the required solution.
