When things get hot, their density typically decreases. This is because the heat causes molecules to move faster, increasing the space between them and therefore reducing the overall density of the material.
Things with a density of less than 1 will float in a substance with a higher density, like water. This is due to the principle of buoyancy, where the buoyant force exerted on an object is greater than the force of gravity pulling it down.
Yes. For every fluid, there are things that float in it ... they just have to be things that are less dense than the fluid. That's how stones float in mercury, logs float in water, and hot balloons float in air.
Cold water has a higher density than hot water. As water cools, its molecules come closer together, increasing its density. Conversely, hot water molecules are more spread out, resulting in lower density.
The density of a hot glue gun stick can vary depending on the type of material it is made from. On average, the density of a hot glue stick is around 0.9 to 1.2 grams per cubic centimeter.
Hot and cold water can separate due to differences in their temperature and density. When hot and cold water are combined, the hot water tends to rise to the top because it is less dense than the colder water below. This process is known as thermal stratification.
Becomes lighter and rises, the principle of hot air balloons.
Things Melt, people go outside lots of fun summer things
Hot fluid flows upward (because its density is lower), causing cooler fluid to flow downward.

the density increases
why do density currents hapen?
the density decreases
The density goes down.
For the same reason that it happens in other fluids. The hot air (in this case) has a tendency to rise, and colder air, to sink, due to differences in density.
What happens is that you can see that the density of a nail is more than the density of water and that the density of a cork is less than that of water.
