    InPH3 there are 3 orbitals bonded to H atom and 1 lone pair of e.Lone pair-bond pair repulsion is more than bond pair-bond pair repulsion so its shape changed to pyramidal from tetrahedral and hence angle reduced from 109 deg to 92 deg.But in PH4+ ion there is no lone pair and hence angle is 109deg .So bond angle inPH4+ion is more than PH3

    The process of dissolution of solid solute in liquid solvent increases concentration of solution. Crystallization occurs when solid solute particles collide with each other. When the rate of dissolution is balanced with the rate of crystallization, dynamic equilibrium is reached at which concentration of solution becomes constant and specified temperature.

    Ethers are a class of organic compounds that contain an ether group—an oxygen atom connected to two alkyl or aryl groups. They have the general formula R–O–R′, where R and R′ represent the alkyl or aryl groups.

    Ethers are liquid at room temperature and are typically colorless, with a sweet smell. The most common type of ether is diethyl ether, which is extremely flammable and was one of the first anesthetics used in surgery.

    Amorphous materials are ubiquitous in natural and engineered systems. An amorphous solid is a liquid that does not flow: its atomic structure is disordered like that of a liquid but it is rigid and holds its shape like a solid.

    Amorphous materials include silica glass and a multitude of other materials of different origins, such as soft glasses (like concentrated emulsions, mousses and colloidal glasses), chocolate mousse or ketchup , various gels or beauty creams. These soft glasses are actually capable of flowing if forced: mayonnaise looks solid in a jar, but can be spread with a knife, just like liquid honey.
