Mock-up image of opening a loot box in a video game. In video game terminology, a loot box (also called a loot crate or prize crate) is a consumable virtual item which can be redeemed to receive a randomised selection of further virtual items, or loot, ranging from simple customisation options for a player's avatar or character to game-changing equipment such as weapons and armour.
Flame coloring is also a good way to demonstrate how fire changes when subjected to heat and how they also change the matter around them. [1] [2] To color their flames, pyrotechnicians will generally use metal salts. Specific combinations of fuels and co-solvents are required in order to dissolve the necessary chemicals.
In the most common type of flame, hydrocarbon flames, the most important factor determining color is oxygen supply and the extent of fuel-oxygen pre-mixing, which determines the rate of combustion and thus the temperature and reaction paths, thereby producing different color hues. Different flame types of a Bunsen burner depend on oxygen supply.
The ability to control fire was a dramatic change in the habits of early humans. [15] Making fire to generate heat and light made it possible for people to cook food, simultaneously increasing the variety and availability of nutrients and reducing disease by killing pathogenic microorganisms in the food.

A flame test involves introducing a sample of the element or compound to a hot, non-luminous flame and observing the color of the flame that results. [4] The compound can be made into a paste with concentrated hydrochloric acid, as metal halides, being volatile, give better results. [5] Different flames can be tried to verify the accuracy of ...

The fire triangle or combustion triangle is a simple model for understanding the necessary ingredients for most fires. [1] The triangle illustrates the three elements a fire needs to ignite: heat, fuel, and an oxidizing agent (usually oxygen). [2] A fire naturally occurs when the elements are present and combined in the right mixture. [3]
