Final answer:
To convert the temperature of dry ice, -77 °C, into kelvin, add 273.15 to the Celsius temperature.
The temperature of dry ice, -77 °C, is equal to 196.15 K.
Step-by-step explanation:
To convert the temperature of dry ice, -77 °C, into kelvin, we need to add 273.15 to the Celsius temperature.
So, -77°C + 273.15 = 196.15 K
Therefore, the temperature of dry ice, -77 °C, is equal to 196.15 K.
