RRB Group-D Model Paper 16 with answers for online practice

Concept:

• Temperature: It is the measure of the degree of hotness and coldness of a body.
• The SI unit of temperature is Kelvin (K).

Fahrenheit and Celsius are measurements of temperature and are related to each other as follows:
C = (F - 32) × $\frac{5}{9}$
Where C is the temperature in Celsius and F is the temperature in Fahrenheit.
EXPLANATION:
Since we need temperature in fahrenheit and celsius to be equal:
Now, let C = F = x
So,
x = (x - 32) × $\frac{5}{9}$
or, 9x = 5x – 160
or, 4x = -160
or, x = -40
Therefore, -40°C = -40°F
