Heat is simply motion of molecules, specifically the vibration of molecules. When air is heated the individual molecules begin to vibrate faster making it, on average, harder for two molecules to get closer together without bumping into each other. This means that a group of air molecules will begin to increase distance amongst themselves, taking up more volume than they would if they were cool.

When happens when air is heated?

It expands, taking up more space, if there is no more space, pressure in the container increases.


Why does air accupy more space when it is heated?

The molecues making up the air receive the energy from the heat, and as they become more excited they spread out and fill more space.


Does warm air take up more space?

yes, as the particles of air are heated, it moves more rapidly, which causes it to expand

When air heats in a bottle you can a balloon?

The air alone is not able to blow up a balloon. When air in the bottle is heated with a balloon on top of it, the air expands due to the heat and moves and finds more space. This in turn will blow up the balloon.


When air is heated the density the air weighs?

When air is heated, its density decreases because the air molecules gain energy and move faster, causing them to spread out and take up more space. This results in the warmer air being lighter than the surrounding cooler air, leading to buoyant forces and causing the warm air to rise.


Does matter expand or contract when heated up?

When heated up, matter typically expands due to an increase in kinetic energy within the atoms and molecules that make up the material. This increased kinetic energy causes the particles to move more vigorously, leading to a larger amount of space taken up by the material, hence the expansion.


Which property measures the space taken up by an object?

The space taken up by an object is called volume.


What is most of space taken up by?

What is most of outer space taken up by?

Most of space is taken up by the rarest, least dense nothingness imaginable.


How do you make air expand when its heated?

When air is heated, the molecules in the air gain kinetic energy and move more vigorously. As a result, they push against the walls of the container, causing the air to expand. This expansion happens because the increased motion of the molecules creates more pressure against the walls of the container, leading to the air taking up more space.
