What does density have to do with convection?
Things with a lower density will float on things with a higher density. If you take a fluid (air or water) and heat it, the portion that is heated usually expands. The same mass takes up more volume and as a consequence the heated portion becomes less dense than the portion that is not heated. Get it? Hope you do!
What happens to the air when heated up?
iit will become less dense
What happens if you push down on a piston in a fluid?
the piston would push air down and fluid up.
Will a liquid sink when its hotter than the liquid around it?
No, usually it will rise, since the density of most liquids will decrease as it is heated up.
What causes pressure in fluid's?
All of the forces exerted by the individual molecules in a fluid add together to make up the pressure exerted by the fluid
What happens to molecules in a heated fluid?
Molecules will rapidly spread apart and move in every direction in the presence of a heated fluid, and tightly bunch up in cooler fluids.

What happens to wood when heated up?
it will take long to be heated up,
What happened with density of gases on heating?
As gases are heated up, its volume increases, resulting in a decrease of density.
What happens to the chemical reaction when it gets heated?
It may speed up when heated.
What happens to particals when heated up?
They vibrate
What happens to the wire when heated?
it goes up
How is heat transferred into a fluid?
When a fluid (liquid or gas) is heated, it expands. The heated fluid is therefore less dense than the fluid around it, so it rises.Colder fluid then sinks down to replace it and this sets up a movement of fluid called a CONVECTION CURRENT.
What happens when the volume of a fluid is heated at the bottom?
if its there long enough and gets hot enough and you drop it in water, it goes kaboom and shoots out its contents-trust me
What happens to leaves when heated?
they shrink and shrivel up
What happens when it is heated?
"It" heats up,unless you were talking about that.
What happens to pressure in a metal spray when heated up?
It heats up
