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 corresponding reading on the Kelvin scale would be 77 K.
To convert a temperature from Celsius to Kelvin, you need to add 273.15 to the Celsius value.
In this case, the temperature of liquid nitrogen is -196 °C.
To find the corresponding reading on the Kelvin scale, you can use the formula:
Kelvin = Celsius + 273.15
Let's calculate it step-by-step:
Kelvin = -196 °C + 273.15
Kelvin = 77.15 K
Therefore, the correct answer is option O: 77 K.
