Why are the state symbols for water and water vapor different?
Water may be present in a liquid state (l), but it may also be present in a gasseos state (g) known as steam, or a solid sate (s) known as ice.
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.
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?
it becomes a solid wich is smaller but denser.
What happenes when a solid turns into a liquid?
When a substance is in liquid from and changes in to a solid it freezes. It is also called solidification

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
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.
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
Clouds form when the water vapor in air condenses as?
paritcles in the atmosphre [s. naruto rocks air condenses to form liquid water or ice crystals

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.
Why are the state symbols for water and water vapor different?
Water may be present in a liquid state (l), but it may also be present in a gasseos state (g) known as steam, or a solid sate (s) known as ice.
Is s liquid a physical property of water?
water physically IS a liquid.
