Question

Minus 30 degree ice or 100 degree water which is more hotter

Answer 1

Temperature is measuring how hot or cold something is, such as the outside air temperature, your body temperature, temperature of water for cooking, boiling, washing, etc.
So, is it cold or hot when the temperature forecast says it will be 5 degrees or it will be 30 degrees? What temperature does water freeze at? Or boil at? What temperature is comfortable for your living room?
Therefore,100 degree water will be more hotter than minus 30 degrees water
