What is grahams law of diffusion?
graham's law of diffusion states that the rates of which gases diffuse at the same temperature are inversely proportional to the square roots of their densities.
What would be a hypotheses about the relationship between molecule size and rate of diffusion?
Diffusion will take place more quickly if the surface area of the cell is larger. For example if you cut 3 pieces of potato, 1cm, 1.5cm and 2cm and soaked them in a chemical such as potassium, the smaller of the potato's will be less affected.
Is swallowing and eating the same thing?
No. Swallowing is a voluntary action that forces solids or liquids, with or without nutritional value, down the oesophagus into the stomach. Eating includes mastication (chewing), and swallowing.
How does molecular size affect diffusion rate?
Rate of diffusion is indirectly proportional to the molecular mass. This means that for a heavier particle, (i.e, higher molecular mass), the rate of diffusion is slower because they would have to travel the same distance with more energy compared to smaller molecules. Imagine a fat man trying to run and a slimmer man, the fat man would require more energy.Read more: What_is_the_relationship_between_the_rate_of_diffusion_and_the_molecular_mass_of_a_substance
What substance can diffuse through a differentially permeable membrane?
Diffusion across a membrane in biology is referred to as 'osmosis' & osmosis is the process by which solvent molecules move from a region of high conc. to low concentration and this can therefore occur only in one direction at a time for a perticular solution. this is a really smart answer im surprised
Do all liquids diffuse the same way?
no because different molecules have different sizes. Smaller molecules will diffuse faster than larger molecules.
What are the properties of Solids, Liquids, and Gas?
Has the same shape
How are solids liquids and gasses the same?
There the same because there the three common states of matter.
How are liquids and solids the same?
Liquids and solids are same in the way that they are made out of the same atoms, just those atoms are being set in a different environment and temperature.
What is a mixture of liquids or solids dissolved into liquids?
It is called a solution. The same general word used for this kind of answer to your question.
How do sound travels through gas?
Compression waves (same as for solids & liquids).
Why are solids USUALLY more dense liquids and gases?
Solids are usually more dense because solids have a smaller volume than liquids or gases, so the same amount of mass is in a smaller volume, making the density greater.
Do all liquids evaporate the same rate?
No
How are liquid mass and liquid volume alike?
Liquids, like solids have a definite volume. While liquids don't have a definite shape, they can take the shape of a container which can be measured the same way as with solids.
How do sound waves travel through gas?
Compression waves (same as for solids & liquids).
Do all liquides way the same?
No, not all liquids diffuse the same way. How each liquid diffuses is dependent what other chemicals are in the liquid.
How does the kinetic energy of solids liquids and gases compare?
Gases have the highest kinetic energy, followed by liquids, and then solids. -apex
