The temperature of liquid nitrogen is -196 °C. What is the corresponding reading on the Kelvin scale?
O 77к
О 146 K
0 127K
• 48 K
0 91 K
The Kelvin scale starts from absolute zero, which is -273.15°C. To convert from Celsius to Kelvin, you simply add 273.15.
So, to find the corresponding reading on the Kelvin scale for -196°C:
-196 + 273.15 = 77.15 K
Therefore, the correct answer is O 77 K.
To convert from Celsius to Kelvin, you simply add 273.15 to the temperature in Celsius. Therefore, to find the corresponding reading on the Kelvin scale for -196 °C, we add 273.15 to -196.
-196 + 273.15 = 77.15
The corresponding reading on the Kelvin scale is 77.15 K.
So, the correct answer is option O 77 K.
