I believe it has something to do with molecules. Heat is caused by the molecules of an object rubbing against each other and causing friction, which is heat. As they do this, they slowly spread the edges of whatever the material is in order to have more room to move. This changes the size of the material, but the amount of molecules remains the same, leaving the material less dense than it was before.
When heat is applied to an object, it's structure becomes more spread out and begins to move rapidly. A good comparison would be a rock to a handful of feathers.
The temperture decreses
the lower the temperature gets the more dense the air becomes.
when temperature of air increases it becomes less dense and expands rising up which causes the pressure to drop
Matter transitions from a liquid to a gas when temperature increases because energy increases. The matter in question becomes less dense and there is an overall rise in entropy.
If a fixed volume of gas increases in temperature, it must increase in volume. If the gas is in a closed system, the pressure inside that system increases instead. When the gas increases in volume, it also decreases in pressure, often rising above colder, more dense gas if possible.
Ocean water gets more dense as temperature goes down. So, the colder the water, the more dense it is. Increasing salinity also increases the density of sea water. Source: Science book.
because their monocles separate causing less density per cubic inch.
less dense
The density of materials depends on the temperature.
The force of gravity affects nearby light, causing a change in temperature.
the lower the temperature gets the more dense the air becomes.
When the water gets warmer the water becomes less dense.
Yes! Increasing the temperature increases the kinetic energy of molecules by vibrating the bonds between atoms. The increase in energy causes the substance to become less dense meaning the particles are more spread out. For example, a solid is the coldest form of a substance so it is the most dense. On the other hand, a gas is the hottest form so is the least dense. Hope this helps!
Because there is less air above, pushing down.
no
This effect occur because warm air is less dense. The higher the temperature the less dense it becomes. As temperature increases, so does the kinetic energy of the particles in the substance.
Volume and Temperature. Higher temperature increases pressure and decreases density. Lower temperature decreases pressure and increases density. (Except with water, in which case ice is less dense than liquid water. [Keep in mind that vapor is still less dense than liquid and follows the rules.] This is the only exception known to me). Higher volume decreases pressure and increases density. Lower volume increases pressure and decreases density.
when temperature of air increases it becomes less dense and expands rising up which causes the pressure to drop
