Do regular and dry ice melt in the same way?
Regular ice is frozen, solid water. When s temperature rises, it turns to water: a liquid. Dry is solid carbon dioxide. When its temperature rises, it becomes a gas instead of first turning to a liquid.
How does boiling affect water s state of matter matter?
Boiling causes water to change from its liquid state to a gaseous state, known as steam or water vapor. This transformation occurs when the water reaches its boiling point, typically 100°C (212°F) at sea level, where the molecules gain enough energy to break free from the liquid's surface. As a result, boiling is a physical change that alters the state of matter from liquid to gas.
Why are the state symbols for water and water vapor different?
State symbols for substances reflect their physical state at a given temperature and pressure. Water is represented as a liquid (l) at room temperature and pressure, while water vapor is represented as a gas (g) when it evaporates at the same conditions. The state symbols help differentiate the physical states of the same substance in various conditions.
Why is entropy of saturated liquid lower than saturated vapor for any pure substance?
Because to perform the change of state from the saturated liquid to saturated vapor ( at constant presure ) you have to add heat in the amount of the substance's evaporation latent heat Qev . At constant pressure, temperature will stay fixed at its saturation temperature and the increase in entropy will be (delta S)ev = Qev/Tsat where (delta S)ev is the entropy increment. Tsat is the saturation absolute temperature of the substance. And so the saturated vapor entropy is (delta S)ev larger than the saturated liquid entropy.
Why water expend s it freezes?
Water expands as it freezes because its molecules form a crystalline structure, causing them to arrange in a way that takes up more space than when they are in their liquid state. This expansion creates gaps between the molecules, leading to an increase in volume.

How would one write out liquid water and water vapor and aqueous sodium chloride and solid sodium chloride in chemical equations?
Phases are denoted with (s) (l) or (g) and aqueous solutions are (aq) ex: H2O(g) - water vapor H2O(l) - liquid water NaCl(aq) - aqueous sodium chloride NaCl(s) - solid sodium chloride
Condensation happens when a gas changes into an?
Condensation happens when a gas or a vapor changes into a liquid or a solid. H2O (v) ----->H2O (l or s) V= vapor L=liquid S=solid
Does water molecules speed up or slow down when water vapor returns to the liquid water s?
Condensation. The transformation of water vapours in liquid water is called condensation, a change of phase.
What are the specific heat values for the three states of water?
water (s) = ice =2.03 J/gC water (l) = liquid water = 4.186 J/gC water (g) = vapor or steam = 1.01 J/gC

How do you write a formula with physical state?
Put a subscript ed letter or letters in parentheses next to the chemical substance. (s) is solid (H2O(s) is ice). (l) is liquid (H2O(l) is liquid water). (g) is gas (H2O(g) is water vapor). (aq) means something is dissolved in water (NaCl(aq)).
The portion of the earth's surface that includes water and water vapor is the...?
The portion of the earthÃ?s surface that includes water and water vapor is known as the Hydrosphere, which makes up about 70% of the earthÃ?s surface.
Is s liquid a physical property of water?
water physically IS a liquid.
How would one write out liquid water water vapor aqueous sodium chloride and solid sodium chloride in chemical equations?
Your question is not so clear; but: - liquid water - (H2O)l - water vapour- (H2O)g - sodium chloride as a solid - (NaCl)s
What is the abbreviation for water vapor?
There is actually no atomic symbol for water vapour ... it is water in another state and water is not an element, it is a compound of hydrogen and oxygen i.e. H2O. Temperature and phase (solid, liquid, gas) do not change this symbol.
