So we know that just like in a balloon or rubber band if you stretch it out you are going to get some extra energy we call elastic energy.

Now not all balloons are going to behave that way, but let's assume for the moment that this balloon does that.

Its the pressure in the blood that is actually causing the vessels to balloon out.

You can use this stored elastic energy to move blood. You can use this for movement energy.

So you go ahead and give a small amount of pressure, maybe a small breath and this balloon gets a little bit bigger, and you note that it's, let's say a small amount of pressure is over there, and it gets a little bit bigger over there so you can put a little X right there.

This is a point cloud.

They're at the pressure door.

It's an economic force it's a technical force.

Well... they're putting the squeeze on.

So now my artery looks a little fat, like a plump little sausage.

It activates what's called the buzzing bridge, or the dog.

(Music)

And it's pressure sensitive to the forces both in the plane of the screen

It's the pressure reg valve again.

Hopefully, that gives you an intuition that if I had some amount of pressure in this situation if I squeeze the volume, the pressure increases.

The pressure, it's spiking.

The mechanical power of the explosion is aggravated by the reactor confinement is aggravated by the reactor confinement whence losing control of it whence losing control of it what would seem to be an advantage what would seem to be an advantage in case of an airplane fall becomes a deadly inconvenience.

The more and more you try to squeeze a balloon if you squeeze it from all directions, it gets harder and harder to do it, and that's because the pressure within the balloon increases as you decrease the volume.

Holding.

But sometimes, carbon based organisms like plants or animals get stuck in the earth.

It is probably plants, except that these have been burned and crushed under pressure.

Pressure's increasing again.

To cause an object to accelerate, or speed up, a force must be applied.

Pressure?

If we know what that force is, and we you know the area of the wall, we can figure out pressure, because pressure is equal to force divided by area.

And to make that, it involves extremes of temperature, extremes of pressure and loads of pollution.

That's fine, it's how we're designed.

So in this case, when our volume goes up, the average pressure or the pressure in the container goes down.

Air lock pressurization complete.

Pressure's steady.

In general, if I have an ideal gas in a container, the pressure exerted on the gas on the side of the container, or actually even at any point within the gas, because it will all become homogeneous at some point and we'll talk about entropy in future videos but the pressure in the container and on its surface, times the volume of the container, is equal to some constant.

Too much pressure. It'll kill it.

Breathing this way is hard because it requires an active movement of our diaphragm and intercostal muscles.

Pressure's approaching critical.

Pressure's increasing again.

Pressure in the primary tank is rising.

There's always an oppressor and an oppressed.

Extra Compression Options

The calcaneal squeeze test evaluates for calcaneal injury, such as a stress fracture.

Chief, we're losing pressure.

Pressure inside the tank is approaching 400 psi.

There's a lot of pressure on you, as organizers, to book them and put them on.
