A material scientist investigates the characteristics of materials and their uses. Nature and human knowledge restrict the number of existing materials on Earth. This signifies that there is a limited amount of material available for use in the production of goods.
Given that they deal with the design and manufacturing of things, mechanical engineers sometimes lack the specialties seen in other branches of engineering. This necessitates a thorough understanding of all elements of engineering.
<h3>Why does Absolute Zero Exist?</h3>
Absolute zero, also known as zero kelvins, is equivalent to 273.15 degrees Celsius, or -459.67 degrees Fahrenheit, and represents the point on a thermometer where a system has the least amount of energy, or thermal motion. But there's a catch: absolute zero is unattainable, But exists as a measure of relativity.
Absolute zero is the temperature at which a thermodynamic system has the least amount of energy. It is equivalent to 273.15 degrees Celsius on the Celsius scale and 459.67 degrees Fahrenheit on the Fahrenheit scale.

Answer with Explanation:
1. Hindi ko kayang mabuhay nang walang kapwa dahil naniniwala akong ang <u><em>pakikisalamuha sa ibang tao ay kailangan para mabuhay nang maligaya at buo ang pagkatao.</em></u>
2. Sang-ayon ako sa pahayag na <em>"No man is an island." </em>Tayo ay nilikha ng panginoon upang magtulungan dito sa mundo. Hindi <u>natin kayang mamuhay nang mag-isa.</u> Nakaugat sa ating mga dugo ang<em> pakikipag-ugnayan sa ibang tao sa lipunan. </em>Ito'y nakabubuti rin sa ating pag-iisip at sa ating kalusugan at pangangatawan.
Answer:
a. Irreversible
b. Impossible
c. Impossible
Explanation:
to determine if a case is reversible, irreversible or impossible we compare the actual efficiency to the maximum efficiency of each case
maximum efficiency of the power cycle
nmax = 1 - TC/TH
nmax = 1 - 400/1200
