All solutes (e.g. Alka-Seltzer) dissolve better in a warmer solvent (e.g. water).
yes.
Powdered juice dissolves faster in hot water, but tastes 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
Cold is what I've found works best.
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.
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.
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.
No, talcum powder will not dissolve in cold water. Talcum powder is insoluble in water, meaning it will not mix or dissolve in water at any temperature.
if you add baking soda to warm or cold water it will dissolve better and faster than salt!
Gases dissolve better in cold water because lower temperatures slow down the movement of water molecules, allowing more gas molecules to dissolve. In contrast, gases dissolve poorly in hot water because higher temperatures increase the kinetic energy of water molecules, making them move faster and reducing the ability for gas molecules to dissolve.
