an endothermic reaction is usually the break down of a product into its reactants. in order for it to be broken down, energy is needed usually in form of heat. for example, when you dissolve ammonium chloride in water, you would notice that the solution would go cold, meaning the heat is being absorbed in order to break down the ammonium chloride. all endothermic reactions have a positive delta H.

What energy change was observed when a seed is added to a supersaturated solution?
Nucleation is an endothermic process.
What happens to the composition of matter when matter undergoes a chemical change?
A chemical change involve a change of composition.

When ice melts it gains energy and is call this type of change?
When ice melts it is called a physical endothermic change.
What type of phase change does a substance absorb energy from its surroundings?
When a substance absorbs energy from its surroundings, it undergoes a phase change known as endothermic. This results in an increase in the substance's internal energy, allowing it to transition from one state to another (e.g., from solid to liquid or from liquid to gas) by absorbing heat from its surroundings.
