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.
We did a science experiment at school and we did the experiment 3 times twice it dissolved in 15 seconds and once it dissolved in 30 seconds but in cold water it took 30 minutes to dissolve
vinegar is acetic acid and if the lollipop is acidic then it will dissolve fast as like dissolve like..
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!
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.
Most chemical salts dissolve faster in hot water than in cold water.

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

The amount of time and speed it takes to dissolve sugar in water and dissolve salt in water depends on the amounts of salt and sugar, the amount of water, and the temperature of the water. The approximate time needed to dissolve the sugar and salt in water is 25 minutes.

Instant coffee dissolves very quickly in hot water.
