That's right.
The probe is indeed spraying water.
It's a special yet not special kind of water.
The non-special part is that it isn't a liquid rich in special substances, it's simply spring water from a spring behind Qingcheng Mountain.
And why is it special?
It's because the instantaneous temperature of this water is 88.3 degrees.
Students proficient in chemistry should all remember.
Most substances expand when heated and contract when cooled, but water has its maximum density around four degrees Celsius.
At this density, water possesses extremely high material stability — its decomposition temperature is above 2000 degrees.
In addition, students who have taken chemistry classes should remember another saying:
Chemical reactions are essentially the breaking of old bonds and the forming of new bonds.
The H-O-H bond in water requires more than 450 kJ/mol of energy to break, which is higher than the bond energy of the C-H bond.
