nitrogen physical changes
physical Water cannot melt because it is a liquid. However, a snowflake or an icicle can melt because they are solid states of water. 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.
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 .
No. It is a physical change. 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.
When water evaporates, it is a physical change.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.
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.
Compression of nitrogen or any gas does not alter the chemical property...only changes involve in physical properties... On compression the gas molecules are come into more close..so it is pressurized..not change its chemical property...and whenever chances is come it s expand ..

Melting icebergs are a physical change because the ice is changing states from solid to liquid without altering its chemical composition.

Chemical, physical is generealy changes between the states of matter, although those are not the only physical changes

During a phase change, the substance transitions between different states of matter (solid, liquid, gas) without any change in the chemical composition of the particles involved. This means that there is no new substance formed and no chemical change taking place, it is solely a physical change.
Yes, matter can change states after a physical change. Physical changes involve changes in the arrangement of particles without altering the chemical composition. For example, melting ice (solid to liquid) and boiling water (liquid to gas) are physical changes that involve changes in state.
