Why the mercury can not rise in a lab thermometer if there is air in glass tube?
Because the pressure of air may be greater than the pressure of the ascending Mercury.
Why the mercury can not rise in a lab thermometer if there is air in the glass tube?
Mercury does not rise in a lab thermometer if there is air in the glass tube because the presence of air creates pressure within the tube that opposes the expansion of the mercury. Without a vacuum, the air pressure prevents the mercury from moving freely up the tube in response to changes in temperature.
You want to know where you can learn a lab technician course?
i wanna learn about lab technician in Lahore city Pakistan
What is the principle of pressure gauge in air conditioning laboratory unit?
Without knowledge of the pressure in the air cond. lab. unit you will not be able to calculate the mass flow. Without the mass flow you cannot do any analysis of the system.
Why don't your bodies collapse due to atmospheric pressure?
Aha! There is the same amount of pressure inside your body pushing out against the air pressure. This is why astronauts outside of their space lab or Shuttle need a pressure suit - to keep their bodies from exploding (there is no air, therefore no air pressure in space.)
How does air exert pressure on the inside of a car tire?
This is one of the first things you learn in Chemistry class. PV=nRT where n and R are constants and pressure is dependent on temperature and volume. The pressure on the walls of the tire is a reflection of how energetic the molecules of air are.
How is earths air pressure different from seas air pressure?
It is different in that the seas don't have air pressure. No air; no air pressure.
How does air pressure affect air movement?
Air pressure affects air movement because air moves from high pressure to low pressure. The air pressure pushes or will press the air around.
Why are labs over pressurized?
there are no labs that i know of that are over pressurized but biology labs or chemical weapons labs or other labs with dangerous substances are negatively pressurized meaning the pressure inside is reduced so when the door opened air would be sucked into the lab preventing dangerous substances in the air to escape the lab.
What forces are being used in a balloon and rocket lab?
In a balloon lab, the force of air pressure within the balloon creates an upward force, allowing it to float. In a rocket lab, the force of thrust generated by the rocket engine propels the rocket upwards. Both labs demonstrate principles related to aerodynamics and propulsion.
What did you learn by doing the thermal energy lab?
Nothing really.
What uses air pressure to work?
air
