Question 25

119°K is equivalent to -154°C.

To convert Kelvin to Celsius, you subtract 273.15 from the Kelvin temperature. Therefore, 119°K is calculated by taking 119 and subtracting 273.15, resulting in -154°C.

A) 32°C

Option A is incorrect because it does not reflect the proper conversion from Kelvin to Celsius. The calculation clearly shows that 119°K does not equal 32°C, which would require adding rather than subtracting from 273.15.

B) -154°C

Option B is correct as it accurately represents the conversion of 119°K to Celsius. The conversion formula (C = K - 273.15) gives -154°C when applied to 119°K, making this the valid choice.

C) 154°C

Option C is incorrect because it suggests a positive Celsius temperature, which is not possible given that 119°K is below the freezing point of water. The conversion calculation does not support this result.

D) -32°C

Option D is also incorrect, as it does not correspond to the conversion from Kelvin to Celsius. The value of -32°C is significantly higher than the actual result of -154°C derived from the correct calculation.

Conclusion

The correct answer is -154°C, as it directly results from the proper application of the Kelvin to Celsius conversion formula. All other options fail to meet the conversion requirement, either by miscalculating or presenting values outside the expected range for the given Kelvin temperature.
