What is a solids molecule spacing?
Solid molecules are tightly packed together with very little spacing between them. The intermolecular forces hold the molecules in a fixed position, creating a rigid structure. The spacing between solid molecules is much smaller compared to liquids and gases.
How much water molecules are needed for it to be visible?
Water becomes visible in large quantities when there are enough molecules to scatter and reflect light, typically in the form of droplets in the air (e.g., clouds, fog) or bodies of water (lakes, oceans). In smaller quantities, such as a glass of water or a stream, water molecules themselves are not visible to the naked eye.
How does cell shape change during osmosis and cell diffusion?
Osmosis effects the volume of a cell. when the cell has equal water molecules in the water aroung it and in the cell it is shaped normally. When there is a lot of salt in the water the cell shrinks because there is less water content in the salty water thus the cell gets rid of the extra water molecules. When there is very little salt content in the water the cell gets bigger because the cell absorbs to much water.
When water evaporates is oxygen emitted?
No. Evaporation is when water liquid changes to water vapor. In the vapor there are still water molecules. The only sense in which there is separation is that water molecules are on average much closer together in the liquid phase than in the gas phase.
Why the change in surface tension is much less when sodium chloride is added to water in place of an equivalent amount of ethanol?
Sodium chloride is an ionic compound that dissociates into ions when dissolved in water, causing no significant change in the cohesive forces between water molecules. Ethanol, on the other hand, is a covalent compound that disrupts the hydrogen bonding between water molecules, leading to a greater change in surface tension.

What is the difference in water molecules in warm water and cold water?
The molecules in warm water are moving quicker, meaning that the hydrogen bonds between the molecules are breaking very quickly whereas the molecules in cold water are moving much slower.
Why isn't sugar infinitely soluble in water?
Sugar is a polar molecule that can dissolve in water due to its ability to form hydrogen bonds with water molecules. However, there is a limit to how much sugar can dissolve in water because eventually the water molecules become unable to accommodate more sugar molecules, reaching a saturation point. This is influenced by factors such as temperature and pressure.
What cause grass to increase or decrease?
The cause of grass to increase/ decrease is how much you water it and not water it, how much sun light it gets and air.
Can balloons hold more water or air?
Water. Because water molecules do not move around to much. How ever air molecules move a lot.
If a fan blows into a pan with water will affect how much water evaporates?
Yes, a fan blowing into a pan of water can increase the rate of evaporation. The moving air from the fan helps to remove the water vapor saturated air above the water surface, allowing more water molecules to evaporate from the surface.
Explain Why water can evaporate from puddles even on cold days?
Because as the water molecules get heated by the sun they start to move faster and faster until they escape from the liquid and become a gas (water vapour). On a cold day or a dau without sun, this process is slower becasue the molecules move slower and find it more difficult to escape from the liquid.
What size is water vapor?
It depends on the amount of water boiled to make that vapor.
Why is it that sodium chloride is insoluble in kerosene?
When sodium chloride dissolves in water it does so because the positive and negative ions are attracted to the polar water molecules. Benzene molecules are not polar so there is much less attraction.
How much water, in the form of H2O molecules, is present in 6 moles of a substance?
6 moles of a substance contain about 3.6 x 1024 water molecules.
How much does water volume increase when it freezes?
Its density decreases from that of liquid water from 1g / cc, to 0.9167 g / ccVolume = mass / densitySo: volume of 1g of water = 1/1 = 1 ccvolume of 1 g of ice = 1/0.9167 = 1.0909 ccSo % increase = increase / original volume = 0.0909 / 1 = 9.09 / 100= 9.09 % increase in volume from liquid water to ice
Can you make octane fuel with rubbing alcohol?
No. Isopropopal alcohol will dry any water out of the fuel system by scattering the h2o molecules, but it will not increase the octane rating, or power of the engine. Too much will lower the combustability
