Explanation:
From the attached phase diagram, one can easily make out the phase in which water exists. Matter generally exists in three physical states which are solid, liquid and gas. Water is a unique compound that can exists in these three states at a given temperature and pressure.
From the attached phase diagram,
- point O is the triple point where the three phases of pure substance co-exists.
- The areas between the curves points at a single phase of matter. Y is a water vapor.
- The lines on the curve denotes two equilibrium phases. For example; X is a phase contain ice and melt water.

Answer:
energy is used to break bonds in reactants and energy is released when new bonds form in products.The law of conservation of energy states that matter cannot be created or destroyed. Whether a chemical reaction absorbs or releases energy there is no overall change in the amount of energy during the reaction.

Sorry if im wrong
Answer:
See explanation
Explanation:
Sublimation refers to the movement of molecules directly from solid into the vapor or gas phase while deposition refers to the movement of molecules directly from the gas phase into the solid phase. The two are opposite to each other.
Frost is formed in a situation where a substance cools to a temperature that is lower than its dew point. In this situation, the vapour is directly deposited on a surface to form a frost without passing through a liquid phase. Hence the name, deposition.
I think it is True. If not I am sorry. Best of luck to you and ur test! :)
