What else can I help you with?
How does temperature affect entropy?
Temperature affects entropy by increasing it as temperature rises. This is because higher temperatures lead to greater molecular movement and disorder, which results in an increase in entropy.
Why does the amount of denitration increase at high temperatures?
At high temperatures, the molecular movement and collisions increase, leading to more opportunities for denitration reactions to occur. This increased kinetic energy can break the nitrate group bonds more easily, resulting in a higher rate of denitration.
What measurement can move rapidly or slowly molecules around?
Temperature can control the speed of molecular movement. Higher temperatures lead to increased molecular motion, while lower temperatures slow down molecular movement.
Does velocity increase in molecular movement with heat?
yes
What do you have to add to a molecular concentration to increase the rate of movement?
heat.
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 factors speed up diffusion?
Factors that can speed up diffusion include increasing the concentration gradient (larger difference in concentrations), higher temperature (which increases molecular movement), shorter distance for diffusion to occur, smaller molecular size, and the presence of a permeable membrane.
How is temperature related to the viscosity of a liquid?
Temperature and viscosity of a liquid are inversely related; as temperature increases, viscosity decreases. This is due to increased molecular movement and reduced molecular attraction at higher temperatures, causing the liquid to flow more easily. Conversely, lower temperatures result in higher viscosity as molecular movement decreases, making the liquid more resistant to flow.
What causes the greatest increase in the motion of molecules in a system?
Increasing the temperature of the system causes the greatest increase in the motion of molecules. This added energy results in faster molecular movement, leading to higher kinetic energy and increased collision frequency among molecules.
Is molecular movement directly related of inversely related to temperature?
Molecular movement is directly related to temperature. As temperature increase, the additional energy is absorbed by the molecules. This energy is converted to motion energy and the molecules will move faster.
Which three phases of H2O is arranged in order of increasing entropy?
The three phases of H2O in order of increasing entropy are: solid (ice) < liquid (water) < gas (steam). Entropy generally increases as a substance transitions from a solid to a liquid to a gas due to the increase in molecular disorder and freedom of movement.
Which will cause an increase in the mean free path for molecules in a sample of gas?
Increasing the temperature or decreasing the pressure will both cause an increase in the mean free path for molecules in a gas sample. This is because higher temperatures lead to increased kinetic energy and faster molecular movement, reducing collision frequency, while lower pressures result in fewer gas molecules in a given space, reducing the likelihood of collisions.
