Question 4

119 K is equivalent to -154°C.

To convert from Kelvin to Celsius, one must subtract 273.15 from the Kelvin temperature. Therefore, 119 K - 273.15 equals -154.15°C, which rounds to -154°C.

A) 32C

This option is incorrect because 32°C is significantly higher than the temperature calculated from 119 K. The conversion formula indicates that temperatures below 0°C are expected when converting from Kelvin at this value.

B) -154C

This option is correct as it accurately reflects the conversion from Kelvin to Celsius. The calculation of 119 K - 273.15 results in -154.15°C, which is rounded to -154°C, confirming that this option matches the temperature derived from the conversion.

C) 154C

This option is incorrect as it suggests a temperature that is far too high when converting from Kelvin to Celsius. The conversion process clearly shows that 119 K results in a negative Celsius value, not a positive one.

D) -32C

This option is incorrect because it does not reflect the proper conversion of 119 K. The temperature derived from the conversion is much lower than -32°C; hence, it fails to represent the accurate Celsius equivalent.

Conclusion

The correct answer, -154°C, is definitively supported by the proper conversion formula from Kelvin to Celsius. All other options fail to align with the conversion, either by being too high or not accurately reflecting the negative temperature derived from the calculation.
