Definitely. Powders are simply solids broken into smaller particles.
As we know, melting is the phase change from the solid state to the liquid state. Thus, we can definitely melt powders.
To pour liquids or powders into a container with a small opening.
There exists at least one (actually, a lot more than one) powder that dissolves in water. However, not every powder dissolves in water. It wasn't clear which of the two you were trying to ask.
You are allowed to bring one two-sided cheat sheet for each team, NOT for each team partner. You are also allowed to bring trays to place you powders and metals on. You are allowed to bring your own writing utensils. You are allowed to bring something to scoop the powders and metals and liquids out of their containers (such as popsicle sticks for powders and droppers for liquids). You are also allowed to bring a magnifying glass. That's about basically all you need. Oh wait, I forgot. These you MUST have. They come in very handy. Good luck! (I did this event this year, got 17th place :])
Water: it will change from ice when melted. Metals and rocks, when exposed to enough heat, will melt into liquids.
A block of frozen water is a solid. Melt the ice and it becomes water. Boil the water and it becomes vapour (steam/gas).
powders dissolve easier in liquids then solids

RalphD Nelson has written: 'Dispersing powders in liquids'
Liquids can't melt. Melting is when a solid turns into a liquid. Since it is already in the liquid state, it can only evaporate, or boil.
This can be done by using the method of evaporation, which is the seperation of solid & liquid.
