Is helium gas cold?
Helium gas can be hot, cold, or anything in between, just like most other substances.
Do solids dissolve better in hot or cold water?
Dissolving is caused by the small rapid movements of the atoms or molecules. The faster they are moving, the better substances dissolve. As the molecules have more energy and therefore move faster in hot water, substances dissolve better there.
Can hot and cold waters mix with food coloring or dye?
Yes, food coloring is able to mix with hot and cold water. Food coloring and water are both polar substances, so that means that they can mix.
Why does he get hot and cold?
All people get hot when they exercise and cold when they swim in cold water, why should he be any different.
Why does smoke fall when it is cold?
Rather than smoke, it is really a misty fog that comes about as the result of evaporation of the colder substance, whether in liquid form (cold water) or solid form (ice). Other substances can be used as well, for example carbon dioxide, nitrogen and more.
Why does cold water sink under hot water?
cold water is denser than hot water. The same is true of most other substances as well.
How pure is your drinking water?
It is clean but not pure, our water contains things from other substances. When you are in different areas your drinking water can taste slightly different!
Why do substances diffuse faster in hot than in cold temperatures?
In hot water molecule were moving around faster so substances diffuse faster than in cold water.
What floats more between cold water and hot water?
The density of cold water is greater than hot water so there will be more substances that will float in it.
Are molecules in hot water different then molecules in cold water?
If you have the same volume of both then there are in cold water more molecules.
Is gas cold?
Helium gas can be hot, cold, or anything in between, just like most other substances.
Is helium gas cold?

Why is speed of oecan current is higher in noon?
In noon, the sun being high in the sky, increases the temperature of the atmosphere. The oceans 'absorbs' the heat from the atmosphere as heat always travels from hotter substances to cooler substances and the water becomes hot. As hot water is lighter than cold water, it rises up. The cold rushes to take the place of the hot water. This rush of the cold water creates fast currents.
Do solids dissolve better in hot or cold water?
Dissolving is caused by the small rapid movements of the atoms or molecules. The faster they are moving, the better substances dissolve. As the molecules have more energy and therefore move faster in hot water, substances dissolve better there.
Is cold water a different color than warm water?
No.
How cold does it have to be for something to freeze instantly?
Different substances freeze at different temperatures. However all substances would freeze (except helium) at Absolute Zero. The time it takes for the substance to freeze would also depend on the mass and heat content of that substance.
Does cold water dissolve salt?
When substances have a high temperature, they have more energy. The more energy molecules have, the faster they move. The molecules in hot water move faster than cold water because of the higher energy. Because the molecules of hot water move faster, they can more easily break apart other molecules of a different substance when they come into contact. The fast moving water molecules can break apart the bonds between the salt crystals so they become dissolved into the water. Therefore, salt water can only dissolve in hot water.
