Temperature: A physical quantity which is used to measure hotness and cold or a measuring of the average of the kinetic energy of an atoms or molecules in the different systems is known is temperature.
The Si unit of temperature is degree Celsius/
Conductivity: Conductivity of an electrolyte solution is a measure of its ability to conduct electricity.
The SI unit of conductivity is Siemens per meter.
Final Answer
Therefore, the hotness of an object is determined by its temperature.
