Sciency questions that I've always wondered about.

answer 1: if the car was completely sealed then the bird would always move with the car regardless if it was in the air, flying or on the seat sitting, however if there was a significant breach in the car- like the windows were roled down, I think it would have to fly as fast as the car to stay with the car.

answer 2: yes you would move with the car because you are attached to the car, but every turn, every accelleration and decelleration, your upper body would sway accordingly.

answer 3: depends on the chemical you put in- on the whole, no I dont think soda would cause a noticable change in either boiling point or freezing point- but try this, dissolve some salt in some water and stick that in the freezer at the same time as a just pure water, the salt water will take a lower temperature to freeze then the pure water.

hope this answered your questions accuratly

Thats really weird if the bird would just splat against the back window…I want to do an experience on all these one day.. somehow…(not with real life birds or people though)

I’m still very confused about the bird question and the body question. How could you move with the car if you’re not TOUCHING it?!!

Oh and I tried asking my 7th grade science teacher she thought I was screwing with her and ignored me

The bird will not stay motionless as the car accelerates. The bird will stay motionless relative to the ground, since there’s no force vector pushing it forwards except air resistance. The air resistance (as it appears to move backwards from the perspective of someone in the car), will speed it up, but not enough.

Consider that when you’re sitting in the car, the thing that makes you accelerate with it is the presence of physical objects - the seat and seat-back - that are firmly attached to the car. They push you along as you accelerate. You can even test this: put a marble on a flat or slightly curved surface in the car. When the car accelerates, the marble will move ‘backwards’, because there is not sufficient friction to cause it to accelerate at the same rate as everything else.

And yes, solvents can change the temperature at which water boils and freezes.

Using a humming bird as an example:

The bird is staying in one place in relation to the air in the car. The air in the car would be moving forward with the motion of the car so the bird would still stay in place in relation to the car.

If the bird is flapping, it would still move forward, even in the car. However, since the bird is not moving and the car is - then, yes, the bird would hit the rear window. We actually experimented with this in high school, the “bird” (not a real one) hit the back window.

If you are sticking half way out of the car, you would still move with it unless you were detached from the lower part of your body.

A thicker liquid would technically have a higher boiling point, but since soda is still a thin substance, it would still have a boiling point of 100C.

all those have been answered but I like the last one I don’t know why, baiscly it boils at the same temp, its not chemically bonded to anything else so it boils when it normally does, if the added substance is a catylist or a salt (forget wht kind but pretty sure its a type of salt) then as long as it chemically is connected to the h20 it can change is properties

I am prety shur that ti will hit the windo
