that means like if you change a game it will be different than what it was
When energy is added during a phase change the energy is used to break molecular bonds.
the colour will change
When salt is added to water to change its color, the salt dissolves in the water and does not directly affect the color of the water.
it will change into blue black colours.
When potassium iodide is added to ammonium carbonate, no significant reaction occurs because potassium iodide and ammonium carbonate are both stable compounds and do not react with each other.
When energy is added during a phase change the energy is used to break molecular bonds.
A black hole is formed and no temperature exists
Then it will either get hotter, or its phase will change (as when ice melts).
it spoils the milk because of the chemicial reaction
It is a physical change because when salt is added to water,it is dissolved in it which only changes its physical appearance.
it happens when •A physical change is reversible, a chemical change is not.•the freezing of water would be a physical change because it can be reversed, whereas the burning of wood is a chemical change - you can't.
