What is the chemistry of hydrogels?
Hydrogels are crystals that suck up water, sometimes 600 or more times their weight in water. These crystals look like tiny pieces of quartz before they're saturated with water and remarkably like clear shredded jell-o when water is added.
Do catalysts affect temperature?
A catalyst affects the speed of a chemical reaction. If the chemical reaction gives off heat, the reaction may affect the temperature, but the catalyst by itself doesn't affect the temperature.
Does temperature does temperature affect viscosity of magma?
High temperature=low viscosityLow temperature=high viscosity
How does temperature affect production?
hoe does CT2 level affect oxogen production
How does the temperature affect how juice and water evaporate?
At higher temperature evaporation is faster.
What are novel uses of light hydrogels for therapeutics?
Hydrogels are compelling shape for devices, as their can be easily used between tissues. They light responsive hydrogels are of particular interests for accurate and controlled systems. hydrogels that can regulate and remodel the wound immune microenvironment in wound therapy with in novel proteins for enginnering (as tissues).

How are hydrogels made?
Hydrogels are made by crosslinking water-soluble polymer chains to create a three-dimensional network that can absorb water. This crosslinking can be achieved through physical or chemical methods. Physical methods include temperature changes or radiation, while chemical methods involve the use of crosslinking agents such as glutaraldehyde or ethylene glycol dimethacrylate.
What product might contain hydrogels?
Hydrogels can be found in a variety of products such as contact lenses, wound dressings, cosmetics, drug delivery systems, and even as a thickening agent in some foods.

Hydrogel (also called Aquagel) is a network of polymer chains that are water-insoluble, sometimes found as a colloidal gel in which water is the dispersion medium. Hydrogels are superabsorbent (they can contain over 99% water) natural or synthetic polymers. Hydrogels also possess a degree of flexibility very similar to natural tissue, due to their significant water content. Common uses for hydrogels include * currently used as scaffolds in tissue engineering. When used as scaffolds, hydrogels may contain human cells in order to repair tissue. * environmentally sensitive hydrogels. These hydrogels have the ability to sense changes of pH, temperature, or the concentration of metabolite and release their load as result of such a change. * as sustained-release delivery systems * provide absorption, desloughing and debriding capacities of necrotics and fibrotic tissue. * hydrogels that are responsive to specific molecules, such as glucose or antigens can be used as biosensors as well as in DDS. * used in disposable diapers where they "capture" urine, or in sanitary napkins * contact lenses (silicone hydrogels, polyacrylamides) * medical electrodes using hydrogels composed of cross linked polymers (polyethylene oxide, polyAMPS and polyvinylpyrrolidone) * Water gel explosives Other, less common uses include * breast implants * granules for holding soil moisture in arid areas * dressings for healing of burn or other hard-to-heal wounds. Wound gels are excellent for helping to create or maintain a moist environment. * reservoirs in topical drug delivery; particularly ionic drugs, delivered by iontophoresis (see ion exchange resin) Common ingredients are e.g. polyvinyl alcohol, sodium polyacrylate, acrylate polymers and copolymers with an abundance of hydrophilic groups. Natural hydrogel materials are being investigated for tissue engineering, these materials include agarose, methylcellulose, hylaronan, and other naturally derived polymers Source:Wikipedia®
Does the Temperature of a poached egg affect it?
Yes. The temperature at which the poached egg is cooked will affect its consistency. The temperature at which the poached egg is served will affect its taste.

Does the temperature of the tennis ball affect the air?
The temperature of the ball does not affect the surrounding/outside air, but it does affect the air inside the ball.
