Heat generated at the core.
Gases cannot form a free surface on their own. However, gases do have a free surface at the boundary between gas and liquid, such as the free surface of the sea, or the boundary between the liquid of a soft drink and each carbon dioxide bubble rising in it.
A protostar forms when gravity pulls the dust and gases in a nebula together.
Neutral gases do not; ionized gases do.
Glass, clear plastics, perspex, most gases
Gases.
Heat generated at the core.
In the chromosphere, gases move due to convection, which involves the rising of hot gases and sinking of cooler gases. These movements are driven by the transfer of energy from the Sun's interior. Additionally, magnetic fields in the chromosphere can also influence the movement of gases, leading to phenomena such as solar flares and prominences.
The transfer of heat energy is what leads to the formation of convection currents in liquids or gases. As a fluid is heated, it becomes less dense and rises, while the cooler, denser fluid sinks. This continuous cycle of rising and sinking creates a circular motion within the fluid, resulting in convection currents.
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.
THE GASES FORM IN BKING IS WHEN IT IS BAKING AND THE HEAT IS RISING FROM WHAT EVER YOU ARE BAKING
In a fire, heat causes the fuel to release gases. The oxygen in the air then combines with these gases, creating a chemical reaction called combustion. This reaction produces heat and more gases, which sustain the fire as long as there is a continuous supply of heat, fuel, and oxygen.
The cool atmosphere condenses the rising water vapor and causes it to fall back to Earth
Greenhouse gases absorb Infrared heat rising from the surface of the earth.
Jupiter's stripes are caused by various storms and the different gases in its atmosphere. Jupiter's atmosphere contains mostly hydrogen and helium, with trace amounts of methane, sulfur, ammonia, and water.
Its a process for hot air rising, and cold air sinking hope this helps!:) Actually, it doesn't have to be air. Convection occurs in most liquids and gases. Magma beneath the Earth's crust is the best example of natural convection that I can come up with.
The foaming of the yeast or other rising agent helps the bread to rise. It fills the bread with gases to keep the dough pushed out while baking evaporates the moisture and causes it to harden. By that point, the gases will have evaporated too, and you are left with the hardened dough which is now known as bread.
