After freezing, the water molecules are further apart than they were as liquid water ... so it needs to be made extremely cold in order for the molecules to come together and condense and even colder ...

By numerically defining the temperature of the freezing point of water to be 273.15K, the thermodynamic temperature of the boiling point is found to be 373.15K, 100 units higher, so that an ...

Picturesque scenes in the snowy outdoors of Guangdong, China, in mid-December: two men demonstrated a fascinating scientific ...

but a 50-50 mix with water lowers the freezing point to minus 35 and raises the boiling point to 223 or higher. When the engine is off, coolant resides in the radiator. When the engine is running ...
