The entropy change (ΔS) for this reaction would typically be negative, as gases have higher entropy than solids. This indicates a decrease in disorder or randomness, which is expected when gases combine to form a solid.
No, evaporation causes a change in the state of matter (liquid to solid) which is a physical change
If the solvent is a liquid, gases, liquids, and solids can be dissolved. Examples are:Gas in liquid: Oxygen in water.Cation of ions). Note also that the visible bubbles in carbonated water are not the dissolved gas, but only an effervescence; the dissolved gas itself is not visible since it is dissolved on a molecular level.Liquid in liquid: Alcoholic beverages are basically solutions of ethanol in water.Petroleum is a solution of various hydrocarbons.Solid in liquid: Sucrose (table sugar) in waterSodium chloride or any other salt in water forms an electrolyte: When dissolving, salt dissociates into ions.Counterexamples are provided by liquid mixtures that are not homogeneous: colloids, suspensions, emulsions are not considered solutions.Body fluids are examples for complex liquid solutions, containing many different solutes. They are electrolytes since they contain solute ions (e.g. potassium and sodium). Furthermore, they contain solute molecules like sugar and urea. Oxygen and carbon dioxide are also essential components of blood chemistry, where significant changes in their concentrations can be a sign of illness or injury.
The liquid that accumulates in the abdomen is called ascites. It can be a sign of liver disease, heart failure, kidney disease, or certain types of cancer. Treatment involves addressing the underlying cause and sometimes draining the fluid.
exothermic: when the reactants can convert potential energy (stored energy) into kinetic energy. flow of energy into surroundings, surroundings get warmer. the reactants have more energy that the products. energy is lost. the change in enthalpy is negative. the energy sign is on the right side of the arrow (in the equation). exothermic reactions are bond forming endothermic: reactants convert kinetic energy into potential energy during the formation of the products. causes a decrease in temp of the surroundings because it is drawing the heat from it. products have more energy than the reactants. energy is gained. change in enthalpy is positive. the energy sign is on the left side of the arrow (in the equation). endothermic reactions are bond breaking note - enthalpy is another term for potential energy or heat content, the words can be used interchangeably
Gas
The entropy change (ΔS) for this reaction would typically be negative, as gases have higher entropy than solids. This indicates a decrease in disorder or randomness, which is expected when gases combine to form a solid.
The sign of ΔG° for the forward reaction is less than 0. The reactant could be a solid and the products could be gasses.
No, evaporation causes a change in the state of matter (liquid to solid) which is a physical change
The melting point of a substance is the temperature at which solid state of a substance co exist in equilibrium with its liquid state. It is also called the freezing point (melting is the same process as freezing, just in the opposite direction, and so the temperature is identical).See Web LinksSee the Web Links for "Answers.com: Melting point" below for more information.The melting point is a point where a solid begins to heat and lose mass. It generally changes from a solid state to a liquid state.
The particles start to give away and they break away from the attraction. This can be seen when boiling water, because when it boils there are bubbles and that is a sign that a new state is being made (gas) and that the particles are breaking away
They had found ice on mars but no sign of a liquid

According to the MSDS HCl is a Liquid. It is also found dissolved in water.
Yes or it may be a sign of hormonal imbalance
