Things (almost everything, including air) becomes less dense when it is heated. So warm air rises, and cold air falls.

What happens to the air when heated up?
iit will become less dense
What does the particle theory suggest about the motion of the particles of solids liquids and gases when they are heated?
When a solid, liquid or gas is heated the particles in the substance speed up and gets less dense. The particles also spreads out.
What does the particle theory suggest about the motion of the particles of solids-liquids and gases when they are heated?
When a solid, liquid or gas is heated the particles in the substance speed up and gets less dense. The particles also spreads out.
How does convection cause an increase in temperature?
it occurs because most liquids and gases become less dense when heated
How does the particles of a liquid behave when heated?
When a liquid is heated, the particles gain energy and begin to move more rapidly. This increased kinetic energy causes the particles to move farther apart and slide past one another more easily. As a result, the liquid expands and becomes less dense.
When water is heated why it gets less denser?
The particles get further away from each other as water is heated therefore making it less dense
What Heated water becomes less blank as it and temperature rises and it and particles spread apart?
It becomes less dense.
Do convection currents form in the mantle when heated materials become more dense?
Actually, heated materials are less dense. When heat is applied to a substance such as liquid, it becomes less dense. It is this less dense and heated material that rises because it weighs less. The part of the mantle that is more dense would be any substance that is cooling and is sinking down.

What does the current do?
A convection current is a cycle. The way the cycle works is when the liquid is heated the particles become less dense as it rises to the top and then it becomes more dense so it comes back down again. Then the process starts again.
Do diamonds become less dense when heat is added?
Yes. They do become less dense provided that the diamond melts. The particles in liquid are less close to each other as compared to in a solid.
Why does heated gas become lighter?
Heated particles are not actually lighter. What happens is that heated particles require more area. This increase in area is observed as an increase in volume. This reduces the number of particle in a given space. This means that the heated air is less dense. Due to buoyancy, things that are less dense "float" on top of denser things. This is why a hot air balloon rises.
Why does a fluid become lss dense when its heated?
On heating the inter molecular space decreases. So, substance becomes less dense on heating.
Do particles make objects denser?
Particles do make objects denser than they normally may be. For example, if you add particles of salt to water, the water will become more dense. Alternately, if you filter impurities out of water it will become less dense.
Why does convection happens?
convection happens because fluids become less dense and expand and riseas they are heated.
