The process of osmosis over a semipermeable membrane.The blue dots represent particles driving the osmotic gradient. Osmosis (/ ɒ z ˈ m oʊ s ɪ s /, US also / ɒ s-/) [1] is the spontaneous net movement or diffusion of solvent molecules through a selectively-permeable membrane from a region of high water potential (region of lower solute concentration) to a region of low water potential ...
A thermal burn is a type of burn resulting from making contact with heated objects, such as boiling water, steam, hot cooking oil, fire, and hot objects. Scalds are the most common type of thermal burn suffered by children, but for adults thermal burns are most commonly caused by fire. [2]
Starch gelatinization is a process of breaking down of intermolecular bonds of starch molecules in the presence of water and heat, allowing the hydrogen bonding sites (the hydroxyl hydrogen and oxygen) to engage more water. This irreversibly dissolves the starch granule in water. Water acts as a plasticizer.
First, the site of the injury should be removed from the source of heat, to prevent further scalding. If the burn is at least second degree, remove any jewelry or clothing from the site, unless it is already stuck to the skin. Cool the scald for about 20 minutes with cool or lukewarm (not cold) water, such as water from a tap. [3]
Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution which in this case is represented by body fluid) to keep the body fluids from becoming too diluted or concentrated.
Drain the rice and rinse again with hot water to get rid of the last of the cooking water. Serve your reduced-arsenic rice. Maybe it takes a little more time, but for the sake of reducing our ...
When a paint coating is applied on a metallic surface contaminated with soluble salts, an osmotic blistering process takes place (Figure 8.10). Osmosis is the spontaneous net movement of solvent molecules (water) through a semipermeable membrane (coating film) into a region of higher solute concentration (the salt contaminated substrate).
A method of cooking where a container of food is placed in or above boiling water in order to heat gradually or to keep warm. [5] baking barding Wrapping meat in fat prior to roasting. [6] barbecuing Cooking meat or fish slowly over a barbecue grill with indirect heat and smoke. basting Periodically pouring liquid over food as it roasts. [7 ...
