Are ice crystals forming on a window physical changes?
Physic
Are the salt crystals produced when a glass of saltwater is left on a window sill for several days a chemical or physical change?
It is a physical change, as salt (a solid solute) comes out of the solution as the water evaporates.
Is steam condenses on a cold window chemical change?
Change in state is a physical change. Condensation is a change in state and is a physical change.
Is water vapor condensing on a cold window a physical or chemical change?
Physical, any change in stat of matter (Water vapor/gas to water/liquid) Is a Physical change.
What is condensation what cause it?
Condensation is what happens after evaporation. Some examples are clouds forming or water beading up on the outside of a cold glass. It is caused by evaporated water cooling. Condensation is the change from a gas phase into a liquid phase. When moist air touches a colder surface, for example a window, the gaseous water loses some of its energy to the colder window and the water vapor in the air goes back to a liquid. It condenses on the window. Evaporation is the change from a liquid to a gaseous state. For example water in a lake is warmed by the sun some of the water molecules receive enough energy to change into a gas (water vapor). When enough of this water vapor gets together it forms clouds.

Is ice crystals forming on window exothermic reaction?
yes
Is dew forming on a window considered a chemical change?
No, it is considered a physical change because chemically, water is still H2O, it has simply changed state by condensing.
Are the salt crystals produced when a glass of saltwater is left on a window sill for several days a chemical or physical change?
It is a physical change, as salt (a solid solute) comes out of the solution as the water evaporates.
If you break a window is it a physical change or chemical change?
physical.
When was The Chemical Window created?
The Chemical Window was created in 2005.
What kind of marijuana has little crystals like tiny window panes on it?
The good kind. The more crystals, the better. The crystals are what get you high I believe
What two main kinds of change that you can observe when chemical reactions occur?
ripping a towel, or breaking a glass window

Change in state is a physical change. Condensation is a change in state and is a physical change.
Is water vapor condensing on a cold window a physical or chemical change?
Physical, any change in stat of matter (Water vapor/gas to water/liquid) Is a Physical change.
Is breaking a window physical change or chemical change?
Physical Change, the window is still a window and you can get it back to its original state by re-melting it (although i dont see why you would want to do this). No new substace was formed, nor anything given off. :)
Is glass metamorphic?
Crystals are the form that minerals take upon solidification. Metamorphic is a term used to describe a rock that undergoes a chemical or mineral transformation from heat or pressure. New crystals can form in rock undergoing metamorphosis, but the crystals themselves are not considered metamorphic.
