The molecules in your book are always moving. Why does the book appear to be still?

The book appears still because the book is solid and the molecules are very close together.

What would happen to a cell in an isotonic solution?
Diffusion occurs in equilibrium, which means the molecules still move in and out of the cell, but the net (overall, total) movement is 0.
Water molecules will no longer pass through the semipermeable membrane once equilibrium is reached true or false?
False. There will still be movement of water molecules across the membrane, but there will be no net movement. This means that the number of molecules coming into the cell will equal that going out, and equilibrium will therefore be maintained.
When there is not enough oxygen for aerobic respiration what is that called?
During times of insufficient oxygen, the cell undergoes glycolysis, where 2 existing molecules of ATP can form 4 molecules and pyruvic acid. This is an insignificant amount compared to 38 molecules of ATP made by the cellular respiration, which is why it is important to always have enough oxygen.
Some materials can move across the cell membrane against a concentration gradient by?
Large molecules such as glucose that cannot cross the phospholipid bilayer can still move across the membrane through transport proteins by active transport. Active transport uses energy to move molecules the bilayer.
What diseases do vaccines cure?
None, they are preventatives not cures. A few, like the rabies vaccine can still work after infection but before symptoms appear.
What is always moving but always still?
Time, for example.
Does moving air has lesser molecules than instill air?
Moving air probably has less molecules than still air because the particles are spread apart in moving air, and there is less of them, while in nonmoving air, it is packed.
Does random movement of molecules stop once equilibrium is reached?
When equilibrium is reached, there is no net motion of molecules. This does not mean that no molecules are moving. In diffusion, this would mean there are equal molecules leaving as are entering.
When equilibrium is reached do particles still move?
No. Molecules never stop moving if they are about absolute zero in temperature.
Are you ever really standing still?
No you have to be dead as when you are alive your heart is always moving.
How still pictures appear to be moving in motion sound?
put them in a series of one after the other movements and flip the quickly
Which molecules will move faster water molecules in a cup of hot soup or water molecules in a glass of iced lemonade?
A mug is a solid, so the molecules that make up a mug will be rigid and essentially not moving. For a glass of cold water, since it is a liquid, will have molecules that flow by each other but still keeps a shape. in the end, the molecules of water are moving faster.
What drives a heat transfer process?
The laws of thermodynamics say that heat moves from warmer areas to colder areas. At the most basic level this is simply an observed and accepted principle. Physics is the science of observing the universe and writing equations for how it works. A theoretical explanation for why heat moves in this manner is: Warmer molecules move more & faster than the cooler molecules. Through their random motion, the molecules that are moving more & faster migrate into the colder areas more often than the colder slower molecules migrate into the warm areas. So, over time heat moves from warmer areas to cooler areas. Maybe this analogy helps: Imagine two separate groups of balls in a large rectangular pan. At the start each group is restricted to their own end of the pan. One group of balls is very active in their area moving in all directions and bumping into each other, but always moving. The moving balls represent the hot molecules. The other group of balls are not moving at all. These represent the cold molecules. Then the game begins and the two groups are no longer restricted to their own areas. The moving balls near the edge of their area will randomly move out of their area toward the area of the non moving balls. Over time more and more of the moving balls migrate/move into the area with the still balls, but they will also begin bumping into the still balls and start them moving. Eventually all of the balls will mingle with each other moving at the same speed. NOTE: The cold molecules would not be still, just moving more slowly but the result will be the same and it's easier to understand the illustration if they are still when the game starts.
Why is it important to leave the water to become completely still before potassium permanganate crystals can be added?
if the water is moving, the spreading of the molecules has the aid of the moving water and the experiment will become meaningless
What will happen if a partially inflated party balloon were heated?
The air molecules would expand, increasing the pressure of the balloon. When anything gets cold, it contracts, and when heated, it expands. Atoms and molecules are always moving - when something is hot, the molecules are moving faster and greater distances. When something is cold, the molecules are still moving, just slowly and at much smaller distances. You won't see much a difference while it's partially inflated, though there would be one. You can see results more drastically by heating a balloon that is near completely inflated. The more air molecules that are in the balloon, the greater the expansion. In other words, the bigger the balloon and more air that's in it, when heated you will see a larger change in the balloon size.
What does fidgety mean?
It means you are unable to sit still and you always have to be moving around restlessly.
Why do liquids and gases flow freely?
Molecules are constantly moving. Even an object sitting perfectly still has molecules that are moving, but these molecules are only moving in small variations, because the bonds between molecules are too strong. With liquids and gasses, the molecules aren't bound to each other hard enough to prevent the movement from affecting the substance.
