What happens when two air masses collide?
When two different air masses collide, they don't mix. They push against each other along a line called air front. When a warm air mass meets a cold air mass, the warm air rises as it is lighter and the water vapour in it condenses at higher altitudes.
How do you demonstrate air masses?
Step-by-Step Directions
- Inflate the two balloons until they are equal in size and tie them off. Attach a piece of string to each balloon.
- Then, attach the other end of each of the strings to the opposite ends of the ruler. …
- Puncture one of the balloons with the needle (or another sharp object) and observe the results.

When two air masses collide what can be accurately said about the boundary?
When two large air masses meet, the boundary that separates them is called a front. Fronts represent fairly abrupt transitions between two large air masses.
What happens when hot air and cold air collide?
When a warm air mass meets a cold air mass, the warm air rises since it is lighter. At high altitude it cools, and the water vapor it contains condenses. This type of front is called a warm front. It generates nimbostratus clouds, which can result in moderate rain.
When two air masses meet there is a?
weather front When two air masses meet together, the boundary between the two is called a weather front. At a front, the two air masses have different densities, based on temperature, and do not easily mix. One air mass is lifted above the other, creating a low pressure zone.
What happens when a cold front and a warm front collide?
When a cold front overtakes a warm front, it creates what's called an occluded front that forces warm air above a frontal boundary of cooler air masses.
What is the purpose of the balloon experiment?
What are the goals? The goal of the project is to demonstrate the power of gas procuded when of baking soda and vinegar are mixed. The goal is for the balloon to be blown up by the gas created.
What is the best evidence that air has mass?
Proving Air Is Matter When you puff air into it, the balloon expands, so you know it is filled with something—air is taking up the space. You'll also notice that a balloon filled with air sinks to the ground. That's because compressed air is heavier than its surroundings, so the air has mass or weight.
What happens when wind collides?
Convergence: When two air masses of the same temperature collide and neither is willing to go back down, the only way to go is up. As the name implies, the two winds converge and rise together in an updraft that often leads to cloud formation.
What do you think can occur when air masses of different temperatures and humidity collide?
A weather front is a transition zone between two different air masses at the Earth's surface. Each air mass has unique temperature and humidity characteristics. Often there is turbulence at a front, which is the borderline where two different air masses come together. The turbulence can cause clouds and storms.
What happens when a cold front collides with a warm front?
When a cold front overtakes a warm front, it creates what's called an occluded front that forces warm air above a frontal boundary of cooler air masses.
What might happen when two air masses come together and form a warm front?
As the warm front approaches, there may be fog or increasing rainfall, and thunderstorms may form, as well. This is due to the (usually) higher humidity in the air of warm fronts compared to that of cold fronts.
What happens when warm air collides with cold air and is forced to rise over the cold dome?
An example of lift is warm air colliding with cold air and being forced to rise over the cold dome. The boundary between the warm and cold air masses is called a front. Another example of lift is air flowing up a mountainside.
What happens to the pressure when you inflate a balloon?
When you inflate a balloon, you're actually putting gases, in this case mostly helium, into an elastic container. As you add more gas, the pressure inside the balloon increases, and in response, the balloon expands… up to a point, that is!
What did you observe after releasing the air from the balloon?
When you release the opening of the balloon, gas quickly escapes to equalize the pressure inside with the air pressure outside of the balloon. As the gases escape from the balloon, the gas particles exert a force on the ground and the air outside of the balloon.
Does air have matter experiment?
One way to prove that air is made of matter is to blow up a balloon. Before you add air into the balloon, it is empty and shapeless. When you puff air into it, the balloon expands, so you know it is filled with something—air is taking up the space. You'll also notice that a balloon filled with air sinks to the ground.
How do air masses affect climate?
When winds move air masses, they carry their weather conditions (heat or cold, dry or moist) from the source region to a new region. When the air mass reaches a new region, it might clash with another air mass that has a different temperature and humidity. This can create a severe storm.
When two air masses of different temperatures meet the result is?
front When air masses with different temperatures meet, they don't mix together. Instead a narrow boundary forms between them which is called a front. A front is a narrow boundary between two air masses. Usually when fronts occur one air mass is moving into an area while another is moving out.
What happens to the air masses during a cold front?
With a cold front, a colder air mass is replacing a warmer air mass. A warm front is the opposite affect in that warm air replaces cold air. There is also a stationary front, which, as the name implies, means the boundary between two air masses does not move.
What happens to a balloon when air is filled in it?
When air is filled in a balloon then the number of the molecules of air inside the balloon increases. As a result more collisions of molecules take place with the walls. This gives rise to high air pressure on the walls which causes the balloon to expand and get inflated.
What happens to the volume or size of a balloon as it rises in the air?
When a balloon goes up higher in the air, its size will increase. Since there's less air in the upper atmosphere, there's less stuff pushing back on the balloon, and hence the pressure is lower, which allows the balloon to expand.
What is the aim of the balloon rocket experiment?
The air trapped inside the balloon pushes out the open end, providing an “action”. The balloon's resulting motion is the “reaction”. In this experiment you will measure and analyze the relationships between the volume of air in a balloon and the distance, speed and average acceleration of its travels.
What happened to the balloon when you blew air into it?
Gas particles exert pressure on the walls of the container in which the gas is filled. For example, when a balloon is inflated, the air inside it expands, thereby exerting pressure on the balloon walls. As a result, the size of the balloon increases.
What is the conclusion of the balloon experiment?
Gases expand rapidly because their particles move at high speeds in all directions. As the carbon dioxide gas fills the bottle, it has nowhere else to go so it begins to fill the balloon. As the carbon dioxide gas fills the balloon, the balloon inflates.
How do air masses affect temperature and precipitation?
It is the same for a warm air mass. As a tropical air mass travels, it brings warm air with it. This affects the weather by raising temperatures and creating sunny, warm spells. Air masses can also cause storms, clouds, and precipitation.
What causes an air mass?
An air mass forms whenever the atmosphere remains in contact with a large, relatively uniform land or sea surface for a time sufficiently long to acquire the temperature and moisture properties of that surface.
What happens when Continental polar and maritime tropical collide?
A maritime tropical air mass, with warm and humid conditions, is meeting up with a continental polar air mass, with cold and dry conditions to the north. The cold and dry air will push warm, moist air up, generating lift and instability, which can develop thunderstorms.
Why do balloons expand when filled with air?
When air is filled in a balloon then the number of the molecules of air inside the balloon increases. As a result more collisions of molecules take place with the walls. This gives rise to high air pressure on the walls which causes the balloon to expand and get inflated.
What happens to the volume of the balloon when it expands?
As the balloon warms the balloon expands and the density of the air inside the balloon decreases. The volume and temperature kept changing in a way that kept pressure constant.
What happens to the volume of air as it rises?
Answer and Explanation: As an air mass rises its volume decreases, as does temperature. When air rises, it enters the upper atmosphere, which is colder compared to air…
