Is boiling water a physical or chemical change?
Provide evidence from the pictures.
When______changes occur,
Written excerpt-The water being boiled is pure water. When the water is heated the kinetic energy of the water molecules increases, meaning that the molecules begin to move faster. As the speed increases they begin to overcome their attractions to the other molecules. This eventually allows the water to change from a liquid to a gas as molecules escape out of the liquid and into the air.
In the written excerpt it indicates that?
The chemical equations shows?
