Answer : The absolute temperature that corresponds to 26 degree Celsius is, 299.15 K
Explanation :
Absolute temperature : It is a temperature that measured from absolute zero in kelvins.
Conversion used from degree Celsius to kelvin is:

where,
K = temperature in Kelvin
= temperature in degree Celsius
Given:
Temperature in degree Celsius =

Now put the value of degree Celsius in above expression, we get:

Therefore, the absolute temperature that corresponds to 26 degree Celsius is, 299.15 K
