What is the process by which gas particles under pressure flow through a tiny opening?
The movement of gas through a small hole into an area of lower pressure is diffusion.
Which is an example of gas effusion?
One example of gas effusion is the release of a gas through a small hole in a container, such as when air slowly escapes from a balloon. Another example would be the diffusion of gas molecules through a porous membrane, like the way oxygen and carbon dioxide diffuse in and out of our lungs during respiration.
When the evidence in a scientific experiment does not support the hypothesis what should the scientist do?
When the evidence in a scientific experiment does not support the hypothesis the scientist:Confirm through repeated experimentation that the evidence is validReject the hypothesisDevelop another hypothesis that is consistent with the valid evidence
What did Robert milikan contribute in science?
he discovered the the electron has a negative charge through an experiment called the oil-drop experiment
What is diffusion and effusion of gases?
Diffusion - when particles move from an area of high to lower concentrationEffusion - when gas molecules escape from their container through tiny holes in the container.
What is the process by which gas particles under pressure flow through a tiny opening?
The movement of gas through a small hole into an area of lower pressure is diffusion.
What is the process where gases move through small pores?
effusion
What is effusions?
effusion is the process where individual molecules flow through a hole without collisions between molecules. effusion is the process where the gas molecules are passed through a small opening to an evacuated chamber
Is confusion how gases move through a room?
i think there is no such CONFUSION in chemistry . but diffusion and effusion .
The movement of gas through a small hole into an area of lower pressure is called?
EFFUSION
How is the effusion rate of gas related to its molar mass?
A process related to diffusion is effusion, the process by which a gas escapes from a container into a vacuum through a small hole. The rate of effusion is also related to root mean square velocity-heavier molecules effuse more slowly than lighter ones. The rate of effusion-the amount of gas that effused in a given time- is inversely proportional to the square root of the molar mass of the gas.

What is constants in an experement?
A constant in an experiment is the object or value that does not change through out the experiment.
An abnormal sounds produced in the lungs as air moves through fluids of the bronchiole tree?
Air is normally able to pass through the bronchial tree normally is the bronchial tree is open via laminar flow. Breath sounds are heard during auscultation of the chest, using a stethoscope. Normal breath sounds are termed as vesicular breath sounds. However, in conditions such as a pleural effusion where there is air within the pleural cavity, the flow of air becomes disturbed. Therefore, there will be absent breath sounds and if the effusion is large, bronchial breath sounds will be heard which are both abnormal.
What did the Miller array experiment's suggest?
The Miller-Urey experiment suggested that the building blocks of life could have formed on early Earth under conditions resembling the primordial environment, through the synthesis of organic molecules like amino acids. This provided support for the theory that life could have originated from non-living matter through chemical evolution.
What does a control group have to do with the independent variable?
the answer to that question is the control group has nothing to do with the independent variable because a control group is some thing in your experiment that has not changed through out your experiment. And a independent variable is some thing in your experiment that you change through your experiment(s)
