Boiling is a physical change because there is no change in the chemical composition of the substance.
physical. you didnt chance the substance atomically. you just melted it
It depends, which chemical are you trying to find the boiling point for? The boiling point of water is 100 degrees Celsius. For any other chemical, if you have the boiling point in Fahrenheit, just use an online converter.
chemical. when it melts, it doesn't mean it changed into a new substance. it just changed physical states! it is still a metal. physical state is a physical property of any substance, so when it changes physical state, as in changes to liquid, solid or gas, it is still the same substance.
no thats physical bc it doesnt result in a new substance, its just a different state of matter. look in ur book lazy!!
No, the boiling of water at any temperature and altitude is a physical property, because water is not changed, it is still H2O.

The melting point is considered a physical property of materials.
a physical change, it's chemical formula is still H2O
Cadmium is a metal and an element. One physical property is that it is silvery gray. Another physical property is that it has a boiling point of 321.07 degrees Celsius.

physical prop: melts in the hand (about 32 degrees celsius chemical prop: Makes alloy with aluminum
