FA 1 Flashcards
Diffusion of one gas into another until the mixing is complete and the composition of the system is homogeneous throughout the system
Spontaneous
Expansion of a gas into an evacuated space
Spontaneous
Expansion of gas from any region of higher pressure into one of lower pressure takes place spontaneously until the pressure distribution is uniform throughout.
Spontaneous
Diffusion of a solute from a concentrated solution into pure solvent, or into a dilute solution, will take place without external intervention
Spontaneous
The conduction of heat along a bar o metal which is hot at one end and cold at the other end.
Spontaneous
The transfer of heat from a hotter body to a colder body by radiation is spontaneous. All the spontaneous processes represent a tendency to approach a state of thermodynamic equilibrium.
Spontaneous
Flow of liquids from a higher to a lower level is a spontaneous process; the flow continues until the two levels are equal and a mechanical equilibrium is attained. The reverse process is not observed to occur.
Spontaneous
When a solute such as ammonium chloride is added to water, it dissolves with the absorption of heat. The dissolution is endothermic and spontaneous while the reverse process where in the solid ammonium chloride separates from the solution with the evolution of heat leaving pure water is not observed.
Spontaneous
TRUE/ FALSE
Spontaneous processes never revert themselves without the intervention of an external agency
TRUE
TRUE/ FALSE
A system in equilibrium under a given set of conditions will not undergo detectable change unless the conditions are altered. Thus the spontaneous processes are not thermodynamically reversible.
TRUE
TRUE/ FALSE
Spontaneous processes have a natural tendency to move towards a state of equilibrium
TRUE
TRUE/ FALSE
All natural processes proceed spontaneously (i.e., without external aid) and are irreversible in character)
TRUE
Water decomposes into hydrogen and oxygen gases with application of electricity.
Non-spontaneous
A spoon dipped in boiling water gets hot
spontaneous
Wood burns to ash after being set on fire
spontaneous
Silverware tarnish when exposed to air
spontaneous
Table salt dissociates into sodium and chlorine ions in water.
spontaneous
water molecules form from hydrogen and oxygen gases
Non-spontaneous
Refers to how it occurs on its own without the help of any external factors.
spontaneous
water always flows from the faucet down the sink.
spontaneous
a cold coffee left on the table will never become hot by itself
spontaneous
a spent battery does not recharge without an external input
spontaneous
TRUE/FALSE
Spontaneity only tells whether a reaction will occur or not.
True
TRUE/FALSE
Spontaneity does not predict the rate of a process (how fast or slow it occurs)
True
