How does air exand when heated?

Answer 1

Hot_Air_Expands">Hot Air ExpandsAs thermal energy increases, the molecules of a substance move faster. These molecules hit other molecules faster and harder and bounce away from collisions faster and harder. Without a container to limit its shape, a gas will simply expand. thank u very much for reading.

Answer 2

When air is heated, the molecules that compose the air move about faster. As they move faster, they bounce off each other further resulting in more space between the molecules. If the air is in a solid container, there is no room for it to expand. This results in higher pressure instead. If it is in a flexible container, e.g. a balloon, the molecules strike against the wall of the container pressing them outward causing the container to expand.

Answer 3

When air is heated it expands just like any other gas or gas mixture. This is because the added thermal energy increases the speed and collision rate of the gas molecules, expanding the volume filled by a fixed number of molecules.

Answer 4

its obvious, that when you donate the temperature or heat the air , the kinetic energy of the molecules of air increase, since their attractions become less and, molecules vibrate randomly and rapidly,so these molecules go away from each other and hence cause expansions.

Answer 5

We know that matter will always expand when exposed to heat.Gas also expands on heating because when heat is supplied to the particles they gain kinetic energy,therefore they travel faster and space out.The volume will be increased on heating though the density will decreased collision in gas molecules also increases when heat is supplied so as a result the gas expand on heating.

Answer 6

due to the intermolecular attraction between molecules is less and the gases are slightly in nature so when heated the volume of the gases are expande

Answer 7

when the air is heated the particles of the hot air collide with each other and go further apart and that is why hot air expands

Answer 8

A gas has little or no forces holding the molecules together, so when heated, they move more rapidly and take up more space (expand).

Answer 9

Yes, air does expand when heated.
