Final answer:
The temperature of 35°C is equivalent to approximately 308.15 K, which can be rounded to 308 K. This is calculated by adding 273.15 (or the approximate value of 273 for simplicity) to the Celsius temperature.
Step-by-step explanation:
To convert the temperature from degrees Celsius to kelvin, you add 273.15 to the Celsius temperature. Since the outside temperature is 35°C, the conversion to kelvin would be:
K = 35°C + 273.15
= 308.15 K (to the nearest tenth). However, for most purposes, it is acceptable to use 273 instead of 273.15 as an approximation. So, the temperature in kelvin can also be approximated to 308 K.
Therefore, 308 K is the correct choice from the options provided and closest to the actual value.
