Why would rising temperature speed up diffusion in a liquid?
Diffusion results from collisions between moving molecules. If the molecules are moving faster, they will collide more frequently. That will make them spread out, or diffuse, more quickly.
Why does hot water hold more dissolved solids than cold water?
the molecules are moving around faster and are more spread out, therefore leaving room to dissolve more solutes. Cold water molecules are moving slow and are close together.
When matter changes from one phase to another what happens to the motion of molecules and how does it impact the spacing of the molecules?
it depends on which way its heading on the scale, if it's becoming more solid the atoms are moving less and compressing together if it' becoming more gaseous the atoms are moving more and expanding
Which best describes a kinetic theory?
atoms and molecules are always moving
Chemical processes store and release blank in the bonds of molecules?
Energy
When the crystal structure of matter begins to collapse into a swarm of freely flowing molecules the matter is moving from the ( blank) state to the (blank) state?
solid to liquid
When a liquid turns into a solid the pattern of the molecules becomes more BLANK?
Orderly
Transcripts are actually what molecules?
blank
As the concentration of molecules outside a cell increases more molecules will enter the cell?
the molecules are moving down their concentration gradient BACK NEXT

What are moving molecules?
Molecules in motion
Are the molecules of a solid moving?
Yes, but the movement is more of a vibration of the molecules. They don't have enough energy for any greater movement.
What happens to the speed of molecules as they absorb heat?
molecules are moving faster and faster so more heat gets absorbed
Why does hot water hold more dissolved solids than cold water?
the molecules are moving around faster and are more spread out, therefore leaving room to dissolve more solutes. Cold water molecules are moving slow and are close together.
What Change is happening as a liquid changes to a gas?
its boiling, the molecular structure of the liquid is changing. The molecules are moving farther apart and moving faster. Gas molecules are fartherest apart and move randomly and rapidly. If you put more air into a balloon it becomes harder because the air molecules are moving faster in a defined space. It explodes when the molecules exert more pressure than the balloon itself can stand.
How does the movement of moleculs affect temperature?
The more quickly and forcefully molecules are moving, the hotter they will be.
