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 correct answer is 77 K.
To convert from Celsius to Kelvin, you simply add 273.15 to the temperature in Celsius.
Therefore, -196 °C + 273.15 = 77.15 K
Since Kelvin does not have a degree symbol, the Kelvin scale reading would be 77 K.
To convert temperature from Celsius to Kelvin, you need to add 273.15 to the Celsius temperature. In this case, if the temperature of liquid nitrogen is -196 °C, the corresponding reading on the Kelvin scale can be calculated as follows:
-196 + 273.15 = 77.15 K
Therefore, the correct answer is option O: 77 K
