Physical Models Activity (I need help)

You have explored some interesting, informative, and amusing examples of models. Now it's time to get creative and make your own model. Here is the requirement checklist for your model:

✔ Model types can include drawings, diagrams, physical models, virtual simulations, or videos.
✔ Models must be created by you, not something selected from an online or outside source.
✔ Submit a presentation, picture, video, or screenshot of your model.
✔ Submit a one-paragraph summary describing the topic you chose, your model, what it represents, how you made it, and the specific science involved. It is important that you are using science terminology and are accurate.
Now that you know how to create and submit your model, you will need to choose a topic for your model. Choose one of the three topics listed below. Select each topic for an overview.

Conservation of Mass
Atomic Theory
Thermal Energy

Answers

The question above wants to assess your ability to create a model to represent a scientific concept. In that case, I can't create the model for you, but I'll show you how to create that template.

First, you must choose one of the topics presented in the question. I suggest that you choose the topic "Conservation of Masses," because of its simplicity, however you should choose the one you are most familiar with.

Next, you should research this topic and look at the factors that make it up.

After that, you can create your template as follows:

Use a software that has ready-made drawings, mainly geometric figures, for you to represent the elements that make up this topic.Use these drawings to represent these elements, place titles that identify them, and add arrows, which direct the viewer's attention to understand the model.

You can see examples of "Conservation of Masses,"  models in the attached figure.

carbon 12 6 6

Explanation:

Pots and pans that are used for cooking are often
made of copper, aluminum, and iron. Explain how metallic bonding makes these
metals suitable for this use.

Answers

Cooking materials are made of copper, aluminum, and iron because they contain free, mobile electrons owing to the metallic bond.

Metallic bonding involves a sea of electrons that is bonded to metal cations by electrostatic attraction. The electrons in the metallic bond are free to move around the material.

Because there are free electrons, when the material is heated, the electrons receive energy and move faster, this energy spreads throughout the material by conduction.

Hence, good conductors of heat such as copper, aluminum, and iron are used for cooking materials.

100.0 grams of an isotope with a half-life of 36.0 hours is present at time zero. How much time will have elapsed when 25.00 grams remains?

Answers

We have that  the time that will have elapsed when 25.00 grams remains is

T=72hours

From the question we are told

100.0 grams of an isotope with a half-life of 36.0 hours is present at time zero. How much time will have elapsed when 25.00 grams remains?

Generally the equation for the Half life  is mathematically given as

Where

[tex]X=\frac{25}{100}\\\\X=0.25\\\\Therefore\\\\\frac{1}{2}^n=0.25\\\\n=2 half lives[/tex]

Therefore

T=2*36

T=72 hours

Hence

 the time that will have elapsed when 25.00 grams remains is

T=72hours
