11. At what point the Fahrenheit temperature is double of Centigrade temperature? [R.A.S./R.T.S.(Pre) 2007]

Correct Answer: (d) 160° C
Solution:

According to formula

C / 5 = (F - 32) / 9 [placing F = 2C]

⇒ 9C = 10C - 160
⇒ C = 160

Hence at the temperature of 160°C, the Fahrenheit temperature is double.

12. The body temperature of a healthy man is - [Uttarakhand P.C.S. (Pre) 2005]

Correct Answer: (a) 37° Celsius
Solution:

The normal core body temperature of a healthy, resting adult human being is stated to be at 98.6 degrees Fahrenheit or about 37.0 degrees Celsius.

Though the body temperature measured on an individual can vary, a healthy body can maintain a fairly consistent body temperature that is around the mark of 37.0 degree Celsius. If we convert 37 degree Celsius to Kelvin, it equals to 310 Kelvin.

13. The normal temperature of human body on the Kelvin scale is - [I.A.S. (Pre) 1995]

Correct Answer: (d) 310
Solution:

The normal core body temperature of a healthy, resting adult human being is stated to be at 98.6 degrees Fahrenheit or about 37.0 degrees Celsius.

Though the body temperature measured on an individual can vary, a healthy body can maintain a fairly consistent body temperature that is around the mark of 37.0 degree Celsius. If we convert 37 degree Celsius to Kelvin, it equals to 310 Kelvin.

14. The normal temperature of human body is 98.4 °F. It's equivalent temperature in °C is- [U.P.P.C.S. (Pre) (Re. Exam) 2015]

Correct Answer: (b) 36.89
Solution:

15. Normal temperature of human body on Celsius scale will be - [41ˢᵗ B.P.S.C. (Pre) 1996]

Correct Answer: (c) 36.9 degree
Solution:

16. Which one of the following scales of temperature does not have a negative value? [U.P.R.O./A.R.O. (Pre) 2017]

Correct Answer: (c) Kelvin
Solution:

The Kelvin scale has no negative values. The Kelvin scale is the best representation of average kinetic molecular energy. When a substance has a temperature of OK (-273.15° C) it is at 'absolute zero' and has no kinetic energy at all because its particles stop moving.

17. A measured temperature in Fahrenheit scale is 200°F. What will be its value in Celsius scale? [U.P.B.E.O. (Pre) 2019]

Correct Answer: (a) 93.3°C
Solution:

18. Solve this question- [U.P.P.C.S. (Mains) 2016]

Correct Answer: (a)
Solution:

19. The value of 40 degrees Celsius in Fahrenheit scale is [64ᵗʰ B.P.S.C. (Pre) 2018]

Correct Answer: (a) 104°F  
Solution:

20. The value of 50°C in Fahrenheit scale is [65ᵗʰ B.P.S.C. (Pre) 2019]

Correct Answer: (b) 122°F
Solution:
