Nitrogen is quite insoluble in water but like all dissolved gases, its solubility in water decreases as the temperature increases. This is why when you perform some experiments in photosynthesis you boil the water to greatly reduce its gas concentration
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.
Nitrogen is cold.
Yes. Cold water does disslove.
Instant coffee granules dissolve faster in hot water than in cold water.
Caffeine is soluble in water - but not HIGHLY soluble. You can dissolve a lot more caffeine in the same volume of water compared to what will dissolve in an equal volume of acetone. It dissolves better in hot acetone than in cold acetone.
Copper Sulphate will dissolve better in warmer water, it will dissolve both faster and it will be possible do dissolve a greater mass of the Copper Sulphate.
yes.
Powdered juice dissolves faster in hot water, but tastes better in cold water.
All solutes (e.g. Alka-Seltzer) dissolve better in a warmer solvent (e.g. water).
Most solutes dissolve better in warm water because the molecules of warm water move faster, so the water molecules and the solute come in contact more often. For solid solutes, it is generally true that you can dissolve more in warm water than cold water (though I'm not sure the above answer states the reason for this correctly). But gasses generally dissolve better in cold water.
They will dissolve much quicker in warm or hot water than in cold water.
It can, but hot water works better because it helps to dissolve grease and hardened food better than cold.
hot water because the molecules are moving faster
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.
Cold is what I've found works best.
Nitrogen is cold.
Dissolve cyanuric acid in a bucket full of water before adding to the pool. The hotter the water the better as the crystals take a very long time to dissolve completly in cold water.
