Is nitrogen change states a chemical or physical change?
nitrogen physical changes
Is melting ice a chemical or physical change explain?
It is a physical change because when you have a chemical change it changes the properties and makes it into a new thing, and it can't be reversed. Physical changes are usually just changes of states (solid, liquid, gas) and a physical change can be reversed.
What are the different changes in matter?
The different changes in matter,basically,are phsical change and chemical change. You must understand that matter can be in any one of three PHYSICAL states, liquid, solid or vapor ( a gas ). Changing physical states is not a chemical change, but a direct result of heat or cold application.
Is evaporation a chemical change during the water cycle?
The water cycle is a physical change. Water changes from a liquid in the ocean to a gas and then back to a liquid when it becomes rain. You must understand that water can be in any one of three PHYSICAL states, liquid, solid or vapor ( a gas ). Changing physical states is not a chemical change, but a direct result of heat or cold application.
Is evaporating sea water a physical chemical or nuclear change?
Evaporating seawater is a physical change. Physical changes affect the form, but not the chemical makeup of a substance. The sea water is undergoing a change in states of matter, not a chemical reaction. You can undo the change by condensing the evaporated water .
What happens to the chemical structure of water when it changes?
It I'm reading your question right the answer is nothing. Water doesn't change its chemical structure when changing states. Only the IM forces are being overcome.
What changes in states of matter?
chemical change
Does freezing alcohol change its molecular structure?
No because physical states of matter changes are physical changes. they are not chemical changing meaning it is still alcohol, just frozen.
Is hydrogen burning a physical or chemical change?
burning in presence or absence of oxygen is a chemical change.
What happens to the chemical structure of water when it change state?
Chemically, nothing changes about water when it changes state. The physical state changes when water freezes into ice or evaporates into steam.
Is nitrogen change states a chemical or physical change?
nitrogen physical changes
Is melting ice a chemical or physical change explain?

Is cabbage juice and vinegar a chemical or physical change?
Chemical, physical is generealy changes between the states of matter, although those are not the only physical changes

How are physical and chemical changes different in two ways?
a physical change can be reversed but a chemical changes is not. you can all tell the different from a physical and chemical change by seeing if the color or if the substances is still in it normal element and it a chemical change if it has been change to a new substances like a burn paper change to Ashes. It is all most a physical change but it can not be reversed back.
Is water condensing a chemical change?
No, it is a Physical Change. Physical Changes are concerned with energy and states of matter. A physical change does not produce a new substance. Changes in state or phase (condensation, melting, freezing, vaporization, sublimation) are physical changes. Other examples of physical changes include crushing a can, melting ice, and breaking a bottle. Chemical changes take place on the molecular level. A Chemical Change produces a new substance. Some examples of chemical changes include combustion (burning) and rusting of a metal.
Why are change of state physical changes?
The identity of the property does not change so the physical properties change but not the chemical
