Molecular movement occurs primarily in gases, liquids, and to some extent in solids. In gases, molecules move freely and rapidly, resulting in high kinetic energy and low density. In liquids, molecules are close together but can slide past one another, allowing for moderate movement and density. In solids, molecular movement is limited to vibrations around fixed positions, leading to lower energy and density compared to gases and liquids.
What else can I help you with?
What is diffusion occurs because of the what movement of molecules?
No, diffusion does not occur because of random molecular movement. It is rather as a result of movement of molecules from areas of high concentration to lower concentration.
What is chemical diffusion?
Chemical diffusion is the movement of molecules or ions from an area of higher concentration to an area of lower concentration, driven by random molecular motion. It is a fundamental process in many biological and chemical systems, influencing the rate at which reactions occur and how substances spread through a medium.
Does an increase in molecular weight speed up molecular movement?
no relation iz between molecular weight and movement which iz a function of temperature only.
Is diffusion a process involving the movement of a substance through a fluid matrix?
Yes, diffusion is the process of a substance moving from an area of higher concentration to an area of lower concentration within a fluid or gas medium. This movement occurs due to random molecular motion until equilibrium is reached.
What do you have to add to a molecular concentration to increase the rate of movement?
heat.
When reffering to molecular transport does movement occur across the cell membrane?
yes, it can occur in various ways. (active transport, simple diffusion,etc.)
What does the greatest molecular motion occur in?
I would assume in a plasma which is the form which requires the most energy to stay in the same state of matter, and therefore an abundance of molecular movement.
What is diffusion occurs because of the what movement of molecules?
No, diffusion does not occur because of random molecular movement. It is rather as a result of movement of molecules from areas of high concentration to lower concentration.
Does the molecular movement created by sound continue forever?
No, molecular movement created by sound does not continue forever. The movement eventually dissipates as sound waves propagate through a medium and lose energy due to factors like friction and absorption.
What is chemical diffusion?
Chemical diffusion is the movement of molecules or ions from an area of higher concentration to an area of lower concentration, driven by random molecular motion. It is a fundamental process in many biological and chemical systems, influencing the rate at which reactions occur and how substances spread through a medium.
How does convective diffusion contribute to the overall transport of substances in a fluid medium?
Convective diffusion helps substances move through a fluid medium by combining the effects of convection (bulk flow) and diffusion (random molecular movement). This process enhances the overall transport of substances by speeding up their movement and distribution within the fluid.
What is temperature a measure of what movement?
"molecular"
What is the effect of heat and cold?
Heat can cause expansion of materials, increase in molecular movement, and chemical reactions to occur more readily. Cold can cause contraction of materials, decrease in molecular movement, and slow down chemical reactions. Both heat and cold can impact the physical, chemical, and biological properties of substances.
Does an increase in molecular weight speed up molecular movement?
no relation iz between molecular weight and movement which iz a function of temperature only.
What is the molecular movement of a liquid?
it just flows
What is the temperature in which there is no molecular movement?
absolute zero
What is heat but a plant?
Heat is molecular movement
