Heat is caused by molecules vibrating and hitting one another. The hotter the air the more the molecules vibrate and the bigger space each molecule needs. This causes the air to expand and its density to fall.
As air cools, the vibrations slow down and the molecules need less room. This causes the air to contract and its density will go up.
What else can I help you with?
What is less dense warm air or cold air?
Warm air is less dense (lighter) than cold air..that is why warm air rises and cold air settles
When cold air moves toward warm air it pushes the warm air where?
When cold air moves toward warm air, it pushes the warm air upward because cold air is denser and therefore heavier than warm air. This creates a lifting mechanism known as cold air advection, which can lead to the formation of clouds and precipitation.
What effect does cool temperature have on air?
Cool temperatures cause air molecules to contract and move closer together, leading to an increase in air pressure. This can make the air feel denser and heavier, potentially affecting weather patterns and airflow. Additionally, cold air has a lower capacity to hold moisture, so it may feel drier than warm air.
Does cool air follow warm air or warm air follow cool air?
Cool air typically follows warm air. Warm air rises and creates an area of low pressure, which is then filled by cooler air moving in to replace it. This movement of air is known as convection.
When a warm air mass meets a cool air mass what does the warm air mass do?
When a warm air mass meets a cool air mass, the warm air mass rises because it is less dense than the cool air mass. This rising warm air can lead to the formation of clouds and potentially precipitation as the warm air cools and condenses. This process is known as frontal uplift.
When warm air meets cool air does the warm air sink?
The cold air pushes under the warm air.
When cold air moves toward warm air it pushes the warm air?
I pushes the warm air upwards.
Air warm rebus?
warm air
What air mass is warm?
a warm air mass is a large body of air that is extremely warm
When was Contract Air Cargo created?
Contract Air Cargo was created in 1983.
What does warm air do?
Warm air rises,and then sinks when the air is cold.
When you shiver do muscles contract to warm you?
True, :)
Warm air and cold air have densities?
Yes! Warm air is less dense, which is why warm air rises. Cold air is more dense so that's why it sinks.
What happened to the air when it is warm?
Warm air will rise.
Which holds more water vapor warm air mass or cold air mass?
The warm air mass
What is less dense warm air or cold air?
Warm air is less dense (lighter) than cold air..that is why warm air rises and cold air settles
Why doesn't a warm air mass under a cold air mass at a warm front?
A warm air mass rises over a cold air mass at a warm front because warm air is less dense than cold air. This results in the warm air mass being forced to rise and cool, leading to the formation of clouds and precipitation at the boundary of the two air masses.
