Mostly, it is to avoid interference from things outside the experiment.
By bare wires i presume that you mean wires not in closed in a protective sheath. As an experiment wires will have to be changed around quickly to see what the results of the connection produce. Once an experiment changes status to equipment production the regulations change to safety. The customer has to be protected from electrical shock. In an electrical experiment safety has to be the responsible of the person doing the experiment.
Studying chemical reactions in closed containers allows researchers to control the experimental conditions more accurately, preventing the loss of reactants or interference from external factors. It also helps in understanding the stoichiometry of the reaction and determining the reaction rate. Additionally, studying reactions in closed containers can provide insights into the energetics and equilibrium of the process.
when energy cannot move through the object(s)
Closed cell foam insulation itself is not inherently toxic. However, some types of closed cell foam may contain chemicals such as isocyanates, which can be toxic if not properly handled and installed. It is important to carefully follow safety guidelines and ensure proper ventilation when working with closed cell foam insulation.
because every aspect is controlled except the lid either being open or closed and this is neither changed through out the experiment.
Bottles of chemicals are kept tightly closed to prevent the escape of harmful vapors into the environment and to minimize the risk of spills or accidents. Opening the bottle only when needed helps to control exposure to potentially hazardous chemicals and maintain the quality and stability of the chemicals inside.
Everyone lives in a biosphere - Earth. Earth is a biosphere.Man-made biospheres are...Biosphere 2 - A laboratory in Arizona which contains 3.15 acres (13,000 m²) of closed ecosystem.BIOS 3 - Aa closed ecosystem at the Institute of Biophysics in Krasnoyarsk, Siberia, in what was then the Soviet Union.Biosphere J (CEEF, Closed Ecology Experiment Facilities) - An experiment in Japan.
In a closed system, neither the energy or matter changes. (Study Island)
It is not important to have closed captions on videos on you tube because they are just subtitles and not necessary.
So that corrosive chemicals don't land on top of your bare feet
The question "What is the WikiAnswers Mentoring Program all about?".
