If a sealed syringe is plunged into cold water in which direction will the syringe piston slide?
Think about what happens to the gas (air) inside the syringe when the temperature decreases. As the gas cools it will occupy a smaller volume and thus the syringe plunger will move DOWN the barrel.
Why does it make sense that if you squeeze the air in a sealed syringe that the pressure will go up?
If you squash something in a sealed container then you are reducing the volume available for it to fit into and the result is that it pushes back (the pressure goes up). It is like forcing air into a bicycle tyre with a pump.
Why you cannot squeeze a sealed syringe full of water?
because all the space in the syringe is taken up by water. If you squeeze the syringe it will break.
Why you cant squeeze a sealed plastic syringe that is completely full of water?
We can't squeeze a sealed plastic syringe full f water because all the space in the syringe has already been occupied by water and as a result, there is no space left to squeeze. If we attempt to do so , then the syringe will burst or crack.
Why does the water in a sealed syringe evaporate when put in hot water?
Heating favors evaporation.

Is the pressure inside the balloon equal to the atmospheric pressure?
Think about this: if the pressure WERE equal, what would happen in the instant when you open the neck of the balloon and whatever pressure is on the inside meets the pressure that is on the outside (atmospheric pressure)? In your experience, what DOES happen?

When vapor pressure equals atomospheric pressure what is the liquid?
The Liquid will turn into gas. The boiling point corresponds to the temperature at which the vapor pressure of the liquid equals the atmospheric pressure. If the liquid is open to the atmosphere (that is, not in a sealed vessel), it is not possible to sustain a pressure greater than the atmospheric pressure, because the vapor will simply expand until its pressure equals that of the atmosphere.

How will you show that air has maximum compressibility?
by showing at what point it stops behaving like air (the pressure at which it condenses to a liquid).You can show that air has maximum compressibility using 3 syringes with one sealed with water, the other with air, and the other with chalk whereby the one with air will allow compression to the highest degree compared to the rest.
Why does the water in a sealed syringe evaporate when put in hot water?
Heating favors evaporation.
Why must a barometer be open to the air at one end and close at the other end?
A barometer is used for measuring atmospheric pressure. The barometer sealed on the top with an open bottom in order to allow air pressure to push down.
If a container is half filled with a liquid and sealed at room temperature and atmospheric pressure then what happens inside the container?
because the other half is not empty it is filled with gas
What are the uses of anaroid barometer?
A barometer is used to measure barometric pressure. An aneroid barometer has a sealed chamber with some air removed, creating a vacuum. A chain, lever, or spring connects a needle to a plastic disc covering the container. The pointer moves left to right as the air pressure increases or decreases.
How does an aneroid barometer measure atmospheric pressure?
A barometer is an instrument used to measure atmospheric pressure. It can measure the pressure exerted by the atmosphere by using water, air, or mercury.An aneroid barometer is a barometer which measures pressure without using fluids!An aneroid barometer is somewhat different and uses a sealed chamber upon which the fluctuating atmospheric pressure acts. Through mechanical means a pointer is moved on a calibrated scale.
