molecules are in constant motions
The total mass remain constant after a chemical reaction.
Avogadro's constant is the number of atoms or molecules of a substance in 1 mole of that substance.
The proportion of hydrogen and oxygen atoms in its molecules.
You can demonstrate that gas molecules are in constant motion by spraying a bottle of perfume in a room. As the perfume molecules disperse, they spread throughout the air, illustrating their movement as they collide and scatter in all directions. Over time, the scent becomes detectable even at a distance, showcasing how gas molecules can travel and mix with surrounding air molecules due to their kinetic energy. This observable diffusion highlights the dynamic nature of gas molecules in constant motion.
*Avogadro's Constant is 6 x 10^23, representing the number of particles (ie. atoms/ions/molecules) in one mole of any substance :)
C. Pressure. The constant collision of gas molecules against the inside walls of a container produces pressure. This pressure is a result of the force exerted by the molecules as they collide with the walls of the container.
Yes, molecules are in constant random motion due to their thermal energy. This movement allows them to collide, react, and interact with other molecules in their environment.
Not true. gas molecules move more rapidly, but all molecules have SOME movement at any temperature above absolute zero.
The temperature and speed remain constant.
Vander Waals constant 'a' represents the attraction between gas molecules, while constant 'b' represents the volume occupied by the gas molecules. 'a' is related to the cohesive forces between molecules, while 'b' is related to the excluded volume due to the size of the molecules. These constants help account for deviations from ideal gas behavior in real gases.
The amount of 1 mole: 6.022 * 1023 (Avogadro's constant)
No, the rates of absorption and diffusion are not constant for all molecules. They depend on factors like molecular size, charge, solubility, and membrane permeability. Larger molecules, charged molecules, and less lipid-soluble molecules typically have slower rates of absorption and diffusion compared to smaller, uncharged, and lipid-soluble molecules.
