Collisions of helium atoms with the walls of a closed container cause what?
Gas Pressure
What is the use of gas measuring tube?
barometer
Can gas be a pressure?
It is unclear what you are asking. A contained gas will always exert pressure, but it would be incorrect to state that gas is pressure.
What is the term that is used for the pressure of each gas in a mixture of gases?
The pressure of each gas in a mixture is called the partial pressure of that gas.
What is the name of the scientific law air pressure and volume?
The scientific law that relates air pressure and volume is Boyle's law. It states that at a constant temperature, the pressure exerted by a gas is inversely proportional to its volume. In other words, as the volume of a gas decreases, its pressure increases, and vice versa.
What is an absorptiometer?
An absorptiometer is an instrument which calculates the rate of absorption by measuring the pressure of a gas.
How do people measure volume?
Of a solid, measuring the quantity of fluid displaced by the object should suffice. Of a liquid, measuring its volume with a measuring cylinder or similar. Of a gas, measuring its mass or volume under conditions of standardized temperature and pressure
Types of exhaust gas measuring devices for automobiles?
2 examples are Gas analyzer-inserted in muffler Mass airflow machine-inserted in muffler Both measure gas emissions released from a vehicle.
What's the difference between blower and fan?
A blower is a machine for moving volumes of a gas with moderate increase of pressure. A fan moves large amounts of gas with low increase in pressure.
Are there any Real life example of ideal gas law?
The ideal gas law is commonly used in everyday situations, such as measuring the pressure of a car tire by using a pressure gauge. Weather forecasting also relies on the ideal gas law to understand how changes in temperature, pressure, and volume affect the atmosphere. Additionally, the ideal gas law is applied in scuba diving to calculate the changes in gas pressure underwater.
What is the meanig of pycnometer?
A gas pycnometer operates by detecting the pressure change resulting from displacement of gas by a solid object. Expanding a quantity of gas at known pressure into an empty chamber and measuring the pressure establishes a baseline.Then a sample is placed in the chamber and the chamber is resealed. The same quantity of gas at the same pressure is again expanded into the sample chamber, and the pressure is measured. The difference in the two pressure combined with the known volume of the empty sample chamber allows the volume of the sample to be determined by way of the gas law. --GOLD APP INSTRUMENTS
Is using a measuring cylinder or gas syringe better to use when the gas is soluble?
measuring cylinder
Why in the terms of gas motion in the air does the pressure rise?
Pressure increases if gas molecules slam into a surface either faster (higher temperature), hit harder (more mass), or more often (larger number of molecules). Pressure decreases if the gas molecules are generally moving parallel to the measuring surface, which is where the venturi effect and lift on wings can come from.
What supports the idea that mass is conserved in a reaction that produces a gas as a product?
Trapping the gas and measuring its mass...
What are the measuring standards when computing density in gases?
Standar conditions for the measurement of gas density is stablished at 0°C and a pressure of 29.92 inches of mercury wich is the average pressure of the atmosphere at sea level.
What is a gas tube used for in a science?
what is a gas measuring tube
You are collecting gas over H2O in an experiment does the atmospheric pressure have anything to do with the pressure inside the gas collection container?
Yes, the pressure inside the collection container will be exactly equal to the atmospheric pressure if the water level in the collection container is level with the rest of the water. If the atmospheric pressure is different, then the pressure inside the collection container will be different, and that will affect how you calculate the amount of gas collected. If the pressure is different due to the difference in altitude of the location, or even different weather, the results will be different. Simply measuring the atmospheric pressure with a barometer will allow you correct for any such differences.
