Hypotheses for Rate of Dissolving Lab

Hypothesis #1 Temperature

 If the temperature of a solvent is higher (higher/lower) then the solute will dissolve more quickly (quickly/slowly) because when the solvent is heated, the particles move faster. These faster moving particles will dissolve the solute more quickly.

Hypothesis #2 Agitation (Stirring)

If the solvent is agitated then the solute will dissolve more quickly(quickly/slowly) because stirring the solvent and solute helps them bump into each other more quickly and therefore dissolve more quickly.

Hypothesis #3 Particle Size

If the particle size of a solute is larger (smaller/larger) then the solute will dissolve more slowly (quickly/slowly) because the solvent particles will only be able to dissolve the outside layer of a larger particle.
