Things (almost everything, including air) becomes less dense when it is heated. So warm air rises, and cold air falls.
Yes, when air is heated, it expands because the particles gain energy and move farther apart, increasing its volume. This expansion causes the air to become less dense and rise.
Convection is the type of heat transfer that involves changes in density. This occurs when heated fluid particles become less dense and rise, while cooler fluid particles become more dense and sink, creating a continuous circulation pattern.
When a solid, liquid or gas is heated the particles in the substance speed up and gets less dense. The particles also spreads out.
When air is heated up, the molecules within the air gain energy and move faster, causing the air to expand and become less dense. This expansion leads to a decrease in air pressure and an increase in volume.
In a hot air balloon, the particles refer to the air molecules inside the balloon that are heated by the burner. When the air molecules are heated, they become less dense and rise, creating lift for the balloon. This process allows the hot air balloon to float in the cooler, denser air around it.
When heated, gases typically expand and become less dense. So, a gas would be least dense when heated.
The particles get further away from each other as water is heated therefore making it less dense
It becomes less dense.
Yes, when air is heated, it expands because the particles gain energy and move farther apart, increasing its volume. This expansion causes the air to become less dense and rise.

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.
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.
When a solid, liquid or gas is heated the particles in the substance speed up and gets less dense. The particles also spreads out.
Gases and liquids rise when heated because the increase in temperature causes the particles in the substance to gain energy and move faster, leading to a decrease in density. This causes the heated substance to become less dense than its surroundings, resulting in it rising.
On heating the inter molecular space decreases. So, substance becomes less dense on heating.
convection happens because fluids become less dense and expand and riseas they are heated.
When air is heated up, the molecules within the air gain energy and move faster, causing the air to expand and become less dense. This expansion leads to a decrease in air pressure and an increase in volume.
