Answer:
Explanation:
i. From solid to liquid (melting)
For melting to occur, heat must be absorbed by the substance being melted. When the substance gains significant amount of heat, its particles begins to vibrate and move on top of one another.
ii. From liquid to solid (freezing or hardening)
In this phase change, heat is removed from the system. This allows for the molecules to lose their kinetic energies and form an ordered arrangement from their liquid or molten state.
iii. From liquid to gas (evaporation)
As randomness continues to increase, more heat is absorbed to break the attractive forces between molecules of liquids. Phase change from liquid to gas is a heat absorbing process.
iv. From gas to liquid (condensation)
In condensation, heat is lost by a substance. To condense or collect gas particles together, heat must be removed from the system. This allows for a diminished kinetic energy among the particles of the system.
Answer : The correct option is, (3) titration
Explanation :
Titration : It is a laboratory process where we have to use the volume of a solution of known concentration to determine the concentration of unknown solution.
Distillation : It is a process in which we used to separate a pure liquid from the mixture of the liquids based on the different boiling points.
Fermentation : It is a chemical process in which the the bacteria, an organism or yeast converts the carbohydrate into an alcohol or an acid.
Transmutation : It is a process in which the nucleus of a chemical elements changes into another.
Hence, the correct option is, (3) titration
Answer:
NAP+ accepts hydrogen and releases oxygen.
That's just from my hunch
Explanation:
The light dependent reactions <em>release</em><em> </em><em>oxygen</em><em> </em>from the hydrolysis of water as a by product.
