Instant coffee granules dissolve faster in hot water than in cold water.
WikiAnswers is not going to do your experiment for you - that's cheating and it's wrong. Plus, you could be expelled for cheating. This is an easy enough experiment to do - just make a hypothesis of which one you think will dissolve the fastest and take 10 minutes to actually try it with hot and cold water. That's about how long it will take you to do the experiment yourself.
vinegar is acetic acid and if the lollipop is acidic then it will dissolve fast as like dissolve like..
Hot water dissolves salt quickly due to increased kinetic energy, which helps break apart the ionic bonds holding the salt crystals together. The higher temperature of the water speeds up this process, allowing the salt to dissolve faster than in cold water.
Heat loss by any route may be expressed in the general equation H = kA(Tc−Ta). where H is the loss in Joules/s, k is the cooling constant, A is the surface area, and Tc–Ta is the difference between coffee temperature and air temperature. it takes about 4 joules of heat for the temperature of one gram of water to increase by 1 degree centegrade.
Because hot water molecules are moving (Or bouncing around) faster , which is the way the heat is generated , to break the tablet up! And water molecules don't move as fast as hot water molecules!
Most chemical salts dissolve faster in hot water than in cold water.

It won't. Put powdered milk in cold water to dissolve.

Adding sugar to cold water is the absolute slowest way to dissolve the sugar. If you're wanting to dissolve sugar at a very fast rate, add some sugar crystals in a hot beverage.

Instant coffee dissolves very quickly in hot water.
Much faster in boiling water.
It depends on the kind of the solid
In order to dissolve chalk in water, vinegar needs to be added. The vinegar has acid in it that eats away at the chalk to dissolve it.
Not all solids will dissolve in water at all. Those that do dissolve do so at different rates, and it's also temperature-dependent.
