Respuesta :
I think you forogt to add the options along with the question. I am answering the question based on my research and knowledge. The conversion that Juan is doing is converting the temperature from degree Celsius to degree Kelvin. I hope that this is the answer that has actually come to your great help.
Answer:
So Juan measured the temperature in Celsius and she converts the temperature in kelvin by adding 273
Explanation:
Here it is given that Juan measured the temperature of the salt water and then she added 273 in measured value
We have to find the type of conversion she is doing
We know that for converting Celsius to kelvin we add 273 in the measured value
So Juan measured the temperature in Celsius and she converts the temperature in kelvin by adding 273
