The pressure increases as the volume decreases, so when the pipe is changed from large to small, the pressure of the gas will increase.
It won't. The pressure within a hollow object may change if the surface area changes, hence the volume. The total pressure acting on the exterior of a solid object may change if the total surface area changes.
volume is the measurement of the amount of space that an object takes up.
the hadron collider has a diameter of 3.8 metres and has a circumference of 17 miles (27 kilometres)
There is no required pressure at which a tornado forms. Large scale low pressure systems play a role in tornado formation, but the low pressure is not a direct cause of tornadoes. On rare occasions, tornadoes can form with air mass thunderstorms that occur in the absence of a large-scale weather system. There is low pressure inside a tornado, but in this case the important part is not how low the pressure inside the tornado is, but how much lower the pressure is outside the tornado. The range of these pressure deficits is not known as very few measurements have been taken.
Nuclear explosive devices have been constructed in sizes from as small as 6 inches in diameter to as large as 80 feet tall by 20 feet in diameter. In other words, they can be nearly any size.
The contraction and relaxation of the smooth muscle in their walls can change their diameter, thus changing the level of pressure (large diameter yields low pressure and smaller diameter yields high pressure).
Obviously the pressure goes up, but there are many other factors in play here. You have only told us one tiny piece of the situation.
how do you measure diameter
No. The pressure drop inside a tornado is not large enough for this to happen. Tornadoes tear houses apart with the power of their wind.
Do you mean blood pressure? Yes it does like for example when you do drugs or something
35 cm
The diameter is twice as large as the radius.
The largest diameter airways are the mainstem bronchi. Smaller-diameter airways are the bronchioles.
Poor diet, stress, and smoking.
Change in air pressure causes the strong winds. In fact, most winds that we experience on Earth are caused by change in air pressure. Usually significant changes in air pressure occur over a large area and therefore it's only a slow change in pressure over distance making light winds. In a tornado, you get a significant drop in air pressure over just a few feet of land. This causes the winds to get excessivly high.
A car window might implode when it is exposed to a large change in pressure. For example, a pressure change during a tornado or while sinking into deep water could cause the window to implode.
it will change from solid to liquid or gas
