What else can I help you with?
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.
Why Camphor can easily be purified by the process of sumlimation and common salt cannot be purified by sublimation?
Camphor is a molecular compound, with a molecular formula C10H16O. Because it is molecular and the solid is "held together" by inter-molecular forces it has a lower melting point 175 C and boling point 204C than sodium chloride mp 800+C. bp 1400+ C. Under gentle heating solid camphor has a a reasonable vapor pressure and sublimes (no melting or boiling required -as it is flammable care is needed.) Sodium chloride a giant ionic lattice held together by strong electrostatic bonds when under heated gently has virtually no vapor pressure and does not sublime.
What is the molecular movement of melting?
During melting, the molecular movement increases as heat is absorbed, causing the solid's structure to break down. This results in the molecules transitioning from a fixed, orderly arrangement in the solid state to a more disordered, fluid state in the liquid phase.
What do you have to add to a molecular concentration to increase the rate of movement?
heat.
What is the order of the phases of water in order from the phase with the slowest molecular movement to the phase with the fastest molecular movement?
The order of the phases of water from the slowest to the fastest molecular movement is solid (ice), liquid (water), and gas (water vapor). In the solid phase, molecules are closely packed and vibrate in place, leading to minimal movement. In the liquid phase, molecules are more mobile and can slide past each other, while in the gas phase, molecules move freely and rapidly, resulting in the fastest molecular movement.
Does the movement of particles increase or decrease during sublimation?
The movement of particles increases during sublimation. This is because sublimation involves the direct transition of a substance from a solid to a gas phase without passing through a liquid phase, leading to an increase in the kinetic energy of particles.
What is temperature a measure of what movement?
"molecular"
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
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
Does velocity of molecular movement reflect kinetic energy?
no
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.

What does Molecular Motion mean?
Molecular motion refers to the movement of molecules in a substance, which is manifested through various forms like translation, rotation, and vibration. This motion is driven by factors such as temperature and energy, and it affects the physical properties and behavior of substances. Understanding molecular motion is crucial in fields like chemistry and physics for explaining phenomena like diffusion and phase transitions.
