| What is Matter made up of? | -Very small, but moving Particles |
| How is Pressure Created? What even is Pressure? | -Pressure only Happens in a Gas State, for 1 Simple Reason - Particles and Move.
-The Particles move Anywhere, and can Bang into Each other and whatever is in their Way, like Walls
-So when they Hit Something, they give a Force Against it. On its own its very Small, but there are Millions of Particles, that all Hit and Collide, creating a Net Force.
-More Particles in that Given Volume = More Often Collisions with the Walls = Pressure is Higher.
-Pressure, simply enough, is a FORCE |
| How can the Temperature Influence the Pressure, in a Sealed Container? [This just means a Closed System] | -The Force, that the Particles will give out when it Hits Something, also depends on how Fast and Often they hit that Wall
-If you Heat up the Gas, then your given them Energy to their Kinetic Energy Store, meaning they will move Faster, hitting the Walls Harder creating more Pressure. The Opposite is True as well |
| How can the Volume Influence the Pressure? | -Increasing the Volume, and not changing the Amount of Gas in, will have the Pressure Decreases, as they will be Smaller Amounts of Collusions, as the Particles need to Travel Further. The Opposite is True. |
| What is the Formula for Constant? What does Constant even Mean? | -Pressure [Pa] x Volume [m³] = Constant
-This Equation will only work if the Temperature is the Same AND if the Amount of Gas stays the Same as Well
-Constant just means The Same. If the Pressure was Increased, then the Volume would Have to Decrease, cause the Temperature hasn't Changed, nor has any Gas Came In [If it has, then this Formula will NOT work] |
| What can happen to a Container, that can Change Volume, [Balloon] if the Pressure Increased more than the Outside Environment? | -If the Pressure Increased inside the Container, then the Container will Expand, as there is more Force that is Pushing the Container to Expand, which is greater than the Outside Pressure, which is trying to Push the Container In.
-So the Container Expands, meaning the Volume also Increases. But then that means the Particles have Further to Travel, therefore Lowing the Pressure as the Volume Increases [Constant]
-So when the Pressure of Inside = Pressure of Outside, the Container will Stop Expanding. The Opposite is True [Lower Pressure Inside --> Container will Decrease in Volume as Pressure is Greater Outside --> Pressure of Both Inside and Outside is the Same --> Nothing Happens] |
| What happens if you 'Do Work' on a Gas? | -Doing Work just means Transferring Energy
-This can happen by either Mechanically eg Bike Pump, or by Heating eg Candle.
-If we use a Bike Pump, then Energy is Transferred [Work is Done] against the Plunger of the Pump, as it is Exerting a Force Against You.
-This gives Energy to the Kinetic Energy Store of the Gas Particles, meaning they get Faster [More Pressure]
-And also the Thermal Energy Store of the Particles will also Increase, which is why if you Pump something up it'll get Warmer. |
