The initial pressure inside a scuba tank is 15 ATM Calculate the final pressure of the tank after it cools from 375 K to 300 K?
If we assume that there is the same amount (weight) of gas in the cylinder and the volume of the cylinder isn't going to change, we can use the simple formula P/T is a constant.
Then T(new) / T(old) = P(old) / P(new) OR P(new) = P(old) X T(new) / T(old) OR (15 X 300) / 375 = 12 Atm

What is the air pressure inside a cyclone?
The air pressure inside a cyclone is typically lower than the surrounding atmospheric pressure. This drop in pressure is due to the strong updrafts and intense low-pressure system created by the rotating winds of a cyclone.
If the heat and pressure inside earth cause a rock to melt what material would be formed?
If heat and pressure inside the Earth cause a rock to melt, the resulting material would be magma. When magma cools and solidifies, it can form igneous rock. The composition of the magma depends on the original rock material and the conditions under which it melted.
When the balloon is up in the air the burner is turned off and the balloon drifts along with the wind What will eventually happen to the air inside the balloon?
As the balloon cools down, the air inside will also cool. This will cause the air pressure inside the balloon to decrease, potentially leading to the balloon descending back to the ground due to the decreased pressure.
What causes a plastic bottle when filled with hot water to contract when a lid is placed on the top?
We have to assume that the lid does not allow air to enter the plastic bottle. When the water is hot, the air above the water is also hot. When the air cools down, its volume decreases significantly. This, in turn, causes the pressure in the bottle to decrease such that atmospheric pressureis greater than the pressure inside the bottle. This causes the bottle to contract since the force exerted on the bottle due to atmospheric pressure is greater than the force exerted on the bottle due to the air pressure inside the bottle. The volume of the bottle decreases until the pressure of the air inside becomes equal to atmospheric pressure. The changes in volume, pressure and temperature can be explained by the equation pV=nRT, where p:pressure of gas V:Volume occupied by gas n:number of moles of gas R:molar gas constant T:Thermodynamic temperature of the gas
Does ice make pressure of soda go up or down?
Ice causes the pressure in soda to go down because it cools and contracts the gas inside the container, reducing the pressure. This can lead to less gas being dissolved in the soda, which can result in fewer bubbles when the soda warms up again.
Why does the can crush when placed in cold water?
When a can is placed in cold water, the air inside the can cools down and contracts, creating a lower pressure inside the can compared to the outside. The higher pressure outside the can then crushes the can as it tries to equalize the pressure inside and outside.
Why does a hot can crush when placed in cold water?
When a hot can is placed in cold water, the air inside the can cools down and contracts, creating a lower pressure inside the can. The higher pressure outside the can then crushes it.
What is the air pressure inside a cyclone?
The air pressure inside a cyclone is typically lower than the surrounding atmospheric pressure. This drop in pressure is due to the strong updrafts and intense low-pressure system created by the rotating winds of a cyclone.
When magma cools deep inside earth?
When magma cools deep inside earth, igneous rockforms.
Why does a bottle collapse when it has heated air?
When air inside a bottle is heated, it expands and increases pressure. If the bottle cannot withstand this increased pressure, it will collapse as the hot air cools down and contracts, creating a vacuum. The difference in pressure between the inside and outside of the bottle causes it to collapse.
What happens to the pressure when cool air cools?
When cool air cools further, the pressure generally decreases. As air cools, its molecules lose energy and move more slowly, resulting in less collisions and a decrease in pressure.
What happens to the air in a car tire as a result of a motorway journey?
During the journey, the tyre heats up and heats the air inside the tyre. The air then slightly increases in pressure. After the journey, the tyre cools down and the air cools down too, restoring the original pressure. It is best to inflate tyres when they are warm so the pressure is correct when they are running.
A water is boiled for a few minutes in a tin can and the can is sealed while it is hot why does the can collapse as it cools?
When water is boiled, it creates steam which expands and increases pressure inside the sealed can. When the can is sealed and then cooled, the steam condenses back into water, reducing the pressure inside the can. The external atmospheric pressure then crushes the can as it is higher than the pressure inside.
What does the lows pressure system do?
rises and cools
How can you put the egg inside the bottle without touching it?
To put an egg inside a bottle without touching it, you can create a vacuum by heating the air inside the bottle before placing the egg on top. As the air cools, it will contract, creating a lower pressure inside the bottle that will suck the egg inside.
How do crush a bottle with ice and cold water?
As the water inside the bottle cools it uses less air pressure than the cool air outside. The results are crushing.
What factors do you think are affecting the gas inside the hot air balloon?
The factors affecting the gas inside the hot air balloon are temperature, pressure, and volume. When the air inside the balloon is heated, it expands, causing the balloon to rise. Conversely, when the air cools, the balloon descends. The pressure of the gas inside the balloon also plays a role in its movement, as changes in pressure can affect the buoyancy of the balloon. Additionally, the volume of the gas inside the balloon can change as the temperature and pressure fluctuate, impacting the balloon's altitude.
