What the density of air inside an open bottle will be they same density of the outside the bottle?

Why does air come out of a bicycle tire when you open the valve even if the valve is pointing up?

Because the air inside the tire is under pressure. Gas always flows from a region of higher pressure to a region of lower pressure. As the pressure inside the tire is greater than the pressure outside, the air always comes out of the bicycle tyre.

Why is the inside of a car hotter than the outdoor temp on a summer day?

Like a greenhouse, a car with closed doors and windows is a closed space. Heat trapped inside a closed car cannot get out fast. Although the sunlight heats up both inside and outside of a car at about the same rate, the heat getting inside the car is trapped in a closed space. It cannot get away as fast as the heat outside, where it's an open space and heat can lose freely. Therefore, the heat inside accumulates much faster than the heat does outside, which is why the inside of a car is hotter than the outdoor temp on a summer day.

How is heat transferred from the inside to the outside of a house?

The heat is transferred by leaving windows open or doors open. When you leave a window or door open The warm and cold air goes through the door and window and goes straight out. The more you open and close a door the more air from outside comes in and the more the air from inside goes out. If you are running the air or the heat the best thing to do is to make sure that there is no windows or doors left open around the house or your just wasting your money. And plus make sure that your home is well insulated that helps a lot because if there are little cracks in the floor or ceiling the air also goes right throught them too. Hope this helps

If you immerse an open bottle of water upside down in a trough of water why does the bottle not empty its contents?

Actually it does empty its content until the level of the liquid inside and outside is the same.

Why when the air is sucked out a bottle it collapses?

When an empty plastic bottle is left open to the atmosphere the air pressure outside and inside the bottle are in equilibrium (does not always mean they are equal, but in this case they are equal). This means that whatever force exerted by the atmosphere on the outside of the bottle is balanced by a force from the inside of the bottle. When one sucks the air out of the bottle one removes the source of pressure and forces within the bottle. The pressure differential between air outside and inside bottle is enough to cause the bottle to collapse.Note that this will not happen so easily with glass bottles because even when one tries to suck all the air out of them, they also experience a tendency to collapse, but their structure is strong enough to withstand the pressure differences.

What is inside when it is outside and what is outside when it is inside?

A door is a common object that fits this description. When a door is closed, it appears as a solid barrier on the outside but allows entry to the inside. When the door is open, the inside becomes visible from the outside, blurring the distinction between the two spaces.

Why a plastic bottle get crushed if it is first heated by putting in hot water keeping its cap open then immediately placed inside a refrigerator by closing its cap?

When the bottle is put in the hot water the air inside it heats up and expands (the atoms become more energised and move farther away from each other). When the lid is put on and it is put in the fridge, the air contracts; the pressure inside the bottle becomes lower than the air pressure outside the bottle and it gets crushed.
