When the air be liquid?
the air will be in liquid state when its pressure is increased and its temparature is decreased. eg: CNG is highly compressible gas.
What is the advantage of gravity die casting over high pressure die casting?
The tooling for gravity casting costs less than pressure die casting but the part cost in pressure die casting is much less. see Sand Casting. Die Casting: In the high pressure, requires a die casting machine to inject molten liquid or semi-liquid metal to a higher rate of die-casting mold cavity filling and solidification under pressure, forming and casting methods obtained. Gravity Casting: Uses the gravity or weight of the metal to fill the cavity producing a metal part. It does not require the use of an expensive die casting machine. The tooling cost is lesser for gravity casting because of the lower pressures needed to produce parts.
What happen if you heat steam?
If you heat steam under pressure you get "superheated steam" under higher than original pressure
What is meant by pressuriser?
pres·sur·ize tr.v., -ized, -iz·ing, -iz·es. 1. To maintain normal air pressure in (an enclosure, as an aircraft or submarine). 2. To put (gas or liquid) under a greater than normal pressure. 3. To design to resist pressure. 4. To pressure-cook. 5. Informal. To subject to excessive stress, strain, or vexation: an executive who was pressurized by a heavy workload.

Is a tank a pressure vessel?
I guess it depends on whether it's sealed or not. If it's open to the atmosphere how can it be under pressure ? If it's sealed it could be put under (positive or negative) pressure so would be, by definition, a pressure vessel IMHO.
Which fuel is stored in tanks it is not under pressure it flows along a pipe to where it is needed?
liquid
Earthes outer core us under low pressure?
It is under lower pressure, however, it is under pressure enough to compress it into a liquid.
Why is lpg filled in cylynders under pressure?
LPG is filled in cylinders under pressure to convert it into a liquid state, which makes it easier and more efficient to transport and store. By compressing the gas into a liquid form, a much larger volume of fuel can be stored in a smaller space, making it more convenient for domestic and commercial use.
Why does water under the boat cannot be siphoned?
Water under a boat cannot be siphoned due to the principle of atmospheric pressure and the need for a continuous column of liquid. Siphoning requires that the liquid be elevated above the discharge point and that the siphon tube is filled with liquid. In the case of water under a boat, the pressure from the surrounding water and the height difference needed for siphoning cannot be established, preventing water from being drawn out effectively.
What happens to liquid placed under pressure?
When a liquid is placed under pressure, its volume decreases slightly due to the compressibility of the liquid, although most liquids are relatively incompressible. Increased pressure can also raise the boiling point of the liquid, allowing it to remain in a liquid state at higher temperatures. Additionally, if the pressure is released suddenly, the liquid may vaporize or form gas bubbles, depending on the conditions.
What does energy pressure mean?
Pressure energy per unit volume is equal to the pressure and per unit mass is equal to the density of the liquid. When an incompressible liquid flows out of a tank in which the pressure is maintained , the liquid under pressure possesses potential energy.
When should the boiling point of a liquid be recorded?
The boiling point of a liquid should be recorded when the liquid reaches a constant temperature at which it changes from a liquid to a gas (vapor) under a specific pressure. This usually occurs when the vapor pressure of the liquid equals the atmospheric pressure.
Is petrol at room temperature and under atmospheric pressure a gas a liquid or solid fuel?
Petrol, or gasoline, at standard temperature and pressure is a liquid.
Is liquid petroleum gas a gas or a liquid?
Under normal temperature and atmospheric pressure conditions propane is gaseous. However, when the temperature is reduced to below −42.09 °C or when it is stored under high pressure (approx 177 psi), it takes the form of a liquid.
Can carbon dioxide be a liquid?
Yes, carbon dioxide can exist as a liquid under certain conditions of temperature and pressure. At atmospheric pressure, it sublimes directly from a solid to a gas (dry ice). However, under high pressure and low temperature, it can exist as a liquid.
When the air be liquid?
the air will be in liquid state when its pressure is increased and its temparature is decreased. eg: CNG is highly compressible gas.
What can be said of a boiling point of a liquid?
The boiling point of a liquid is the temperature at which the vapor pressure of the liquid equals the atmospheric pressure, causing the liquid to change into a gas. It is a characteristic property of the liquid and can be influenced by factors such as pressure and impurities in the liquid.
