Extra Credit - Everyday Examples of Gas Law
You observe gas law everywhere. Why? We are surrounded by gas (air). For example, car tires expand on a hot day. This can be explain by Charles' Law. As temperature rises, the volume of tire increases. For extra credit, find some examples of gas law around you (that's not already shared) then share with your classmates and your teacher. I look forward to your examples. |
