How does one or more of these topics relate to your life outside of chemistry class?

In this last exam module, we will review the material you learned in the previous four modules to help with your comprehension of material for the exam. In your initial post to the discussion, respond to the following prompts:
Think back over the last four modules. Which topic made the most sense to you and why? How would you explain this topic to a layperson (someone who has never taken a chemistry course)?
Which topic made the least sense to you?
How does one or more of these topics relate to your life outside of chemistry class? In other words, how are these topics relevant in the real world?
Share two or three study tips that you plan to utilize while studying for this exam.
Least Sense – Limiting Reactants in Everyday Life
Most Sense – M9. Discussion: Conceptual Problem Solving

What if there was an inverse relationship between the temperature and the volume?

According to Charles’s law, the volume of a gas is directly related to its temperature in kelvins at constant pressure and the number of moles. In your initial post to the discussion, respond to the following prompts:
What if there was an inverse relationship between the temperature and the volume? How do you think the world might be different? How would this change our day-to-day lives?
Pick one of the following questions and try to answer it using one of the laws you learned in this module:
How do spray cans work?
Why do you need to fill up your tires with air on a cold day?
Why do soda cans explode?
When you inhale, your diaphragm increases in volume. How does this allow you to breathe?
How does a syringe fill?
How does filling a basketball with air increase its volume?

What if all atoms had the same electronegativity values?

Electronegativity is defined as the relative ability of an atom in a molecule to attract shared electrons to itself. We use differences in electronegativity to account for certain properties of bonds. In your initial post to the discussion, answer the following questions:
What if all atoms had the same electronegativity values? How do you think bonding between atoms would be affected?
What are some differences we would notice?
