The mechanical advantage of a device refers to

Chemistry
1 answer:
Savatey [412]3 years ago
4 0

Answer:

Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. The device preserves the input power and simply trades off input forces against movement to obtain a desired amplification in the output force. The model for this is the law of the lever.

Boyle's Law expresses the pressure-volume
Colt1911 [192]

Answer:

\large \boxed{\text{175. atm}}

Explanation:

Data:

p₁ = 1.00 atm; V₁ = 350.      L

p₂ = ?;             V₂ =     2.00 L

Calculation:

\begin{array}{rcl}p_{1}V_{1} & = & p_{2}V_{2}\\\text{1.00 atm} \times \text{350. L} & = & p_{2} \times\text{2.00 L}\\\text{350. atm} & = & 2.00p_{2}\\p_{2} & = & \dfrac{\text{350. atm}}{2.00}\\\\& = &\textbf{175. atm}\\\end{array}\\\text{It would take a pressure of $\large \boxed{\textbf{175. atm}}$ to compress the gas.}

The alchemical, medical, and technological traditions were precursors to chemistry. State a contribution that each made to the d
Kisachek [45]

Alchemy was a form of early chemistry that aimed to transmute base metals into gold and to create an elixir of longevity or eternal life.

Despite these connotations of the mythic and mystical, alchemical follow contend a crucial role within the evolution of contemporary science.

Historically, alchemy refers to each the investigation of nature and an early philosophical and religious discipline that combined chemistry with metal work. Alchemy additionally encompassed physics, medicine, astrology, mysticism, spiritualism, and art.

Chemistry in medicine:

Major contributions to health care have been made possible by chemistry. The development of new drugs involves chemical analysis and synthesis to form new compounds.

Chemistry contributes to the preparation of materials for surgery (sutures, artificial skin, and sterile materials). The sutures used in many surgeries today do not have to be removed, because they simply dissolve in the body after a period of time. Replacement blood vessels for heart and other types of surgery are often made of chemicals that do not react with the tissues, so they will not be rejected by the body and this was made possible with the help of the chemistry.

Chemistry in technologies:

The Iron Age, saw the prevalence of iron increase as the major metal of choice for cutting tools and weapons. Iron was slower to evolve as a material because it required higher temperatures to work the metal. This shift saw a change in smelting practices, improved furnace technologies, and also the development of forging, as opposed to the casting techniques used in the Bronze Age.

Now a days, in big industries, the machines which are made up of big metal sheets or metals, are given shape with the help of fire, by the process of Smelting. The industries tried to make plastics afterwards.
