Boiling point is a physical property.
no. when water boils it is a physical change, because the actuall chemical structure is still H2O, it is just in the form of steam.
It is a physical property of water.
Water boils at 100 degrees Celsius and freezes at 0 degrees Celsius.
I think that's just a physical change, because the water in whatever state, liquid, ice or vapor, is H2O definitely correct!
Water at sea level boils at 212 degrees F or 100 degrees C, but as you boil your water higher and higher above sea level, the temperature needed to boil water lowers. Interesting point: Climbers ascending the highest mountains find that in the high altitude, water will not boil hot enough to cook food.

Boiling is a physical phenomenon, a change of phase.
It is a physical change when water boils. See also related answers.
no it is the molecules in the water moving fast and bumping into each other
Because it just is. Because no chemical reaction takes place when water boils. It simply changes physical form from liquid to gas.
Water boils at 100 degrees Celsius and freezes at 0 degrees Celsius.
Physical. Ice is simply the solid form of water. If it were a chemical change, then ice would not be water.
