Ihave multiple questions! 1.) a model of a molecule can you imagine what a molecule looks like. what are two ways that this model is different from the object it represents? 2.) how can theories change over time? 3.) why can’t you use a model to learn everything about an object? everyone in my house refuses to me so sorry if there’s a lot of questions i’m horrible at science and math

I'm not sure about the rest but for question 2:

A theory is an attempt to come up with a big picture of all we know so far. It also drives future research as people do experiments to see if what the theory predicts actually happens. When experiments don’t support the theory, you have to change the theory and try again. That’s how science works. We come up with a “best guess” (theory), and then do research to test it’s accuracy. As we discover contradictions, we adjust the theory to take those into account, and then start testing the validity of the new theory.

answer:   you might love summer weather, but you don’t want it to feel like the sun is inside your car. but a hot car that just won’t seem to cool down might be a bigger of a problem than you think. your car relies on being at the right temperature.
