Question

(Practice work, not graded)

1. Identify an object in your house that contains a physical system and list three questions you could use to define the system.


2. Use the law of thermodynamics to explain why an ice cube melts in a cup of hot tea.


3. The unit states that systems are not only part of engineering, but also other parts of society, such as financial systems, political systems, etc. Could using systems thinking be helpful for these kinds of systems as well? Explain your answer.


4. Why do you think that engineering students are encouraged to think about uses for technology beyond entertaining society?


5. Create a short poem or haiku (a poem with 5 syllables in the first line, 7 syllables in the second, and 5 in the third) to explain a problem you are currently trying to solve. Do not use more than 20 words to express the problem.




(Please explain answer, I really don't understand)

Answer 1

Answer: ALL CAREFULLY ANSWERED CORRECTLY.

Step-by-step explanation:

1) A loaf of Bread PHYSICAL SYSTEM

✓ How can the environment affect the edibility of the bread

✓ What are the constituents that makes up the bread

✓ What process is involved in these constituents mixing to form the loaf.

2) The law of thermodynamics makes us to understand that when heat/energy passes through a system, the systems internal energy changes with respect to the conservation of energy law. That is energy lost = energy gained. Typically, ice would melt in a cup of hot tea because of the thermal energy in the molecules of the hot tea. When you heat a material, you are adding thermal kinetic energy to its molecules and usually raising its temperature. The temperature of the ice raises due to the kinetic energy added to it and it melts to water.

3) The theory of systems view the world as a complex system of interconnected parts. If we consider the society; (financial systems, political systems, etc) we will agree that they individually have their own components and it's the summation of this components that makes the system, this implies that system thinking could be applicable in this kinda of systems as long as they are made up of components.

4) Technology has boosted every sector of our lives and it has the capacity to do more. Restricting it's importance to entertainment alone would be an underusing of its potentials. Engineering students infact should not need any drive to be encouraged about maximizing all it can do in shaping our world.

5) ~ Nature shows its splendid soul

~Never ceases to leave us in amazement

~And we are in love
