Differentiate between emulsoid and suspensoid in terms of reversibility?
Emulsoids are reversible sols that form reversible gels, meaning they can revert back to sol form with the addition of suitable solvents or conditions. Suspensoids, on the other hand, are irreversible as they do not revert back to sol form once gel formation occurs.
What is solid sol?
A solid sol is a colloid where the continuous phase and the disperse phase are solids. An example of a solid sol is a pearl. A colloid is a dispersion of particles of one substance throughout another. The dispersed substance is called the disperse phase and the substance it is dispersed in is called the disperse phase.
How does pyrite exhibit magnetism and what are the properties associated with this phenomenon?
Pyrite exhibits magnetism due to its iron content. When exposed to a magnetic field, pyrite becomes weakly magnetic. This property is known as paramagnetism. The properties associated with this phenomenon include the ability of pyrite to be attracted to a magnet, albeit with a weak force, and its tendency to align itself with the magnetic field.
What are the different types of colloids?
The 3 types of colloidal system are: 1. Lyophilic colloids 2. Lyophobic colloids 3. Association colloids
What are the materials necessary for the gel apparatus?
To set up a gel electrophoresis apparatus, you will need a gel casting tray, gel comb, gel tank, gel tank lid, power supply, buffer solution, gel image documentation system, and agarose powder for making the gel. Additionally, you will need the DNA samples to be analyzed and loading dye to facilitate sample loading onto the gel.
What is sol gel reversal?
Sol-gel reversal is a process in which a material that was previously formed through the sol-gel method is converted back to its liquid sol precursor form through various means, such as exposure to heat or chemical treatments. This process allows for the modification or recycling of sol-gel derived materials.
What member of the solar system never exhibits phases to earth?
That would be Sol, the Sun.
What are the advantages of sol-gel process?
Key advantages offerred by the sol gel process 1.it uses relatively low temperature 2.it can create very fine powder 3.it produces compositions not possible by solid-state fusion

What is the changing of the sol and gel phases of the cytoplasmic matrix can result in organelle movement called?
The changing of the sol and gel phases of the cytoplasmic matrix that results in organelle movement is called cytoplasmic streaming. This process involves the reversible conversion of the cytoplasm from a more fluid-like sol phase to a more gel-like phase, allowing organelles to move along with the flowing cytoplasm.
Why sol-gel synthesis is unique in preparation of nano materials?
Sol-gel synthesis is unique in the preparation of nanomaterials because it allows for precise control over the composition, structure, and morphology at the nanoscale through wet-chemical processes. This technique enables the formation of homogeneous solutions that can transition into solid networks, facilitating the production of materials with high purity and uniformity. Additionally, sol-gel processes can be easily modified to incorporate various dopants or functional groups, enabling the tailored design of materials for specific applications. This versatility makes sol-gel synthesis a valuable method in creating advanced nanomaterials.
How amoeba locomote by sol-gel theory?
hi friends this may help you,Sol - gel theory is proposed by hyman . It helps some protozoans to move. it is basically consists of some steps which are as follows:-1) The cytoplasm inside the cell is capable of changing into different forms i.e. from fluid to solid and vice versa. When the cytoplasm is in fluid state, it is known as plasma sol, and the more solid or gel like state is called the plasma-gel.2)The interchange of plasma sol to plasmagel is known as Sol-Gel theory and is responsible for amoeba movement.3) When the cytoplasm is in solid or gel like state, there is no locomotion. Movement takes place only when the cytoplasm is in fluid state. This way the amoeba "drags" itself and this movement is known as amoebic movement.4)The locomotion in the amoeba is effected by the formation of temporary finger-like processes of pseudopodia (false-feet, greek, pseudos, false + podos, foot).5)The plasma-sol changes into rigid plasmagel (gelates) at the anterior end and at the posterior end the plasma-gel changes into plasmasol (solates) causing a forward streaming of the more fluid plasma-sol.6)That is why in actively progressing specimens the plasma-sol is continuously rapidly streaming forward, while the plasma-gel is practically everywhere at rest forming, so to say, a tube within which the plasma-sol flows.7)It the course or a granule or crystal fairly straight course either until it reaches or nearly reaches the inner surface of the plasma-gel at the tip of an advancing pseudopod, then it deflects to the right or to the left, upward or downward and sooner or late, directly or indirectly comes into contact with plasma-gel into which it finally changes.8)Other granules are similarly coming and changing it to plasma-gel after attaching to it behind the crystal under observation. As more of these are coming in the same way the position of the first recedes from the anterior and approaches the posterior end of the amoeba. When it reaches this end it gradually moves inward and enters in the plasma-sol, after which it moves forward and the whole processes is again repeated.9)This gives an idea about the movement of the plasmasol and plasmagel. From this, the phenomenon of locomotion can be easily deducted.****************************KEVIN (Jr M.P.L) KAKINADA A.P*************************
What is protoplast and spheroplast?
a protoplast is aliving substance of the cell. it has the same consistency with that of the egg and is a colloidal substance with a sol-gel manner.

What is difference between sol and gel and emulsion?
Sol state is a liquid state .The colloidal particles repel each other. Gel state is more jellylike. The colloidal particles attract each other. emulsion are colloidal system in which both dispersed phase and dispersed medium are in liquid state .
