At 19.9 degrees Celsius, we dissolve a salt crystal.

The Red dot on the graph in the image above represents the time it took to dissolve this salt crystal and the temperature at which it dissolved.
What temperature is represented by the red dot?
Enter the number of degrees Celsius only; no units.

The red dot represents the melting point of the element, which as stated is approximately 19.9 degrees Celsius and how long it took for the heat to properly completely dissolve it.

The question kind of answers itself however, is there a way to re-word it or is there a different answer you're looking for?

did anyone actually do this? like if anyone has submitted this i rly need .
