What is the difference between effusion and diffusion in chemistry?
Effusion and diffusion are both processes by which particles move from an area of high concentration to an area of low concentration. The key difference is that effusion specifically refers to the movement of gas particles through a small opening, while diffusion is the overall movement of particles in a substance.
Does a gas escape through a tiny opening into a vacuum during effusion?
Yes, a gas can escape through a tiny opening into a vacuum during effusion. Effusion is the process by which gas molecules pass through a small opening into a vacuum due to their random motion. This happens because of the difference in pressure between the gas inside and the vacuum outside.
What is the difference between pleural effusion and pulmonary embolism?
A pleural effusion is a build up of fluid between the (visceral and parietal) layers which line the lungs and chest cavity. Whereas....... A pulmonary embolus is a sudden blockage in a lung artery caused by a blood clot that travels to the lung from another part of the body. NB: - Pleural effusion = problem in visceral and parietal layers - Pulmonary embolus = problem in lung artery
What is the relationship between the rate of effusion of a gas and its molecular weight, according to the statement that "the rate of effusion of a gas is proportional to" something?
According to Graham's law of effusion, the rate of effusion of a gas is inversely proportional to the square root of its molecular weight. This means that lighter gases will effuse faster than heavier gases.
Parapneumonic pulmonary effusion?
DefinitionParapneumonic pulmonary effusion is an build up of fluid between layers of the tissue lining the lung and the chest cavity, which develops in the setting of pneumonia.
What part of speech is infiltrate?
Infiltrate is a verb.
What is plural effusion?
The plural form of the noun 'effusion' is effusions.
What is the definition of infiltrate?
Infiltrate v. -to filter in or through; penetrate
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
What is the medical term meaning abnormal accumulation of fluid or other material within the lung that can be seen on xray or other radiologic evaluation?
An infiltrate is an accumulation of fluid or other material seen in the lung on imaging.
Is lung effusion always cancer?
Long effusion is not always cancer
Relationship between gas's molecular weight and speed of effusion?
Higher is the molecular mass lower is the rate of effusion, when mass increases by 4 times rate decreases to one half (Graham's law of diffusion).
