Hydrogen bonding causes water molecules to connect . The energy required to break multiple hydrogen bonds causes water to have a high heat of vaporization; that is, a large amount of energy is needed to convert liquid water, where the molecules are attracted through their hydrogen bonds, to water vapor, where they are not.
Chemical weathering rocks may decompose or dissolve and at the same time change in compostion through a certain chemical process to form residuals materials. Mechanical weathering happens when rocks disintegrate or breaks down into smaller pieces through physical forces. (rain, snow, freezing)
pie
its is used to drink
Pweeeeeeee
according to my calculations it explains the high melting point
Copper has both chemical and physical properties. You will need to specify which property you are asking about
physical property happens by itself or from things in nature. chemical property happens by outside.
Thickness is a physical property without any relation with chemical composition or chemical changes.
Yes , it should or else it is a physical property
you can observe it without changing it.
It is physical. The wire changes shape, but it is still made of the same materials.
its physical change.to explain,the conversion of solid to liquid is physical
Physical changes is change in property. Ex) change from solid to liquid....ice to water. Chemical change changes to different substances. Ex) rotting of fruit.
Explain why energy is necessary to chemical reactions, and describe some common sources of energy.

No.
both physical and chemical change occur
