Actually, when there is warm air, like in a balloon it will expand. When you go outside, the balloon will shrink if it is cold outside. When you go back into the warm indoors, the balloon will go back to its normal size.
do you mean fills with air? if so then its the lungs
to pull in air and break out air
As you go up in elevation, the local air pressure drops, because there is less air above you to push Dow (gravity) to produce the pressure. Less pressure allows the air to expand.
The cooler air inside the balloon would increase in temperature, causing it to expand and potentially burst the balloon. This is because gases expand when heated.
Yes, the more temperature an object has the farther apart the molecules move.
Helium is the element commonly used to expand small objects and make them float. Its low density allows it to lift objects, such as balloons, creating the buoyant force necessary for them to rise in the air.
The function to be closed, to let in air, to let objects or living things through.
No, not all objects expand when heated. Most objects do expand when heated, but there are exceptions such as water between 0°C and 4°C, which contracts when heated. The expansion or contraction of an object when heated depends on its material properties.
Heat causes a gas (like air) to expand. If the gas is in a closed container, the pressure will increase instead. Hot air also rises because it is lighter than cold air.

When objects vibrate, they create sound waves that travel through a medium such as air, water, or solid materials. The vibration causes the molecules in the medium to compress and expand, transmitting the sound energy to our ears where it is perceived as sound.

Tires create friction, which in turn creates heat. Heated objects expand.

Marshmallows are mostly air puffed sweetened gelatin. When the air pressure outside of the mallow goes down, the air inside begins to expand. The further out of equilibrium it goes, the larger the mallow will expand until all of the air inside has escaped.
