The first step in blanching green beans Broccoli being shocked in cold water to complete the blanching. Blanching is a cooking process in which a food, usually a vegetable or fruit, is scalded in boiling water, removed after a brief timed interval, and finally plunged into iced water or placed under cold running water (known as shocking or refreshing) to halt the cooking process.
Scalding is a type of thermal burn caused by boiling water and steam, commonly suffered by children. Scalds are commonly caused by accidental spilling of hot liquids, having water temperature too high for baths and showers, steam from boiling water or heated food, or getting splattered by hot cooking oil. [4]
Most scalds result from exposure to high-temperature water, such as tap water in baths and showers, water heaters, or cooking water, or from spilled hot drinks, such as coffee. Scalds can be more severe when steam impinges on the naked skin, because steam can reach higher temperatures than water, and it transfers latent heat by condensation ...
Why can't you boil your suspect water? Boiling can eliminate bacteria, another concern in contaminated water systems. What's dangerous is when the water is full of volatile organic compounds ...

The depth of penetration depends on the frequency of the microwaves and the tissue type. The Active Denial System ("pain ray") is a less-lethal directed energy weapon that employs a microwave beam at 95 GHz; a two-second burst of the 95 GHz focused beam heats the skin to a temperature of 130 °F (54 °C) at a depth of 1/64th of an inch (0.4 mm) and is claimed to cause skin pain without lasting ...
[2] [11] It should be performed with cool water 10–25 °C (50.0–77.0 °F) and not ice water as the latter can cause further injury. [11] [50] Chemical burns may require extensive irrigation. [2] Cleaning with soap and water, removal of dead tissue, and application of dressings are important aspects of wound care. If intact blisters are ...
Water is said to "boil" when bubbles of water vapor grow without bound, bursting at the surface. For a vapor bubble to expand, the temperature must be high enough that the vapor pressure exceeds the ambient pressure (the atmospheric pressure, primarily). Below that temperature, a water vapor bubble will shrink and vanish.
