Is boiling point a physical intensive physical extensive or a chemical?
When a liquid reaches boiling point it goes through a phase change, liquid to gas. Phase changes do not change the nature of a chemical so it is a physical change. This physical change can sometimes be caused by a chemical change though.
Is a melting wax a physical or chemical property?
Physical change. The wax was solid and now it is a liquid. All phase changes are physical changes.
Substance changes from solid to liquid?
This physical phenomenon (a change of phase) is called melting; during melting the chemical nature of molecules is not changed but the bonds between molecules are weakened.
Is dissolving a drink mix in water a physical or chemical change?
chemical
Physical or chemical humidifier putting moisture into the air?
The moisture is just water vapor, so you are getting a phase change from liquid to gas. Phase changes are physical changes. For a vaporizer to produce a chemical change it would have to do something drastic like convert the water in to H2 and O2.
Is phase changes physical or chemical?
Both
When water changes phase is it chemical or physical?
Physical, as it remains water.

Are melting butter and melting ice cream are both physical change or chemical change?
They're both physical changes. Phase changes are always physical changes. Chemical changes only involve chemical reactions - a change in the identity of the substance. That's why phase changes are physical changes. Ice cream remains ice cream when it melts.
What type of change occur when water changes from a solid to a liquid?
its a phase change
Is melting ice a physical change or chemical change?
Physical; all phase changes are physical changes because the composition does not change.
How can you tell if a physical reaction is occuring?
During a physical change the chemical molecule is not affected; physical changes are changes of phase or form.
If water is boiling is it a chemical change or a physical change?
It is a physical change. All phase changes are physical, not chemical. The chemical composition of water does not change when it changes from a liquid to a gas, or for that matter, to a solid.

Is a boiling point an example of chemical properties?
No. Anything related to phase changes is a physical change.
