Rate of dissolution

The speed at which something dissolves is called 

• Rate
• Solution 
• Solute
• Surface area

We can increase the rate a solute will dissolve by 

• Heating it, Crushing it Stirring it
• Heating it, cooling it crushing it
• Stirring it, Crushing it cooling it
• Smelling it, crushing it, stirring it

This spreads the solvent's molecules around the solute and increases the chance of them coming into contact with it

• Heating
• Stirring
• Cooling
• Crushing

What part of a particle touches the water

• The inside 
• outside
• both inside and outside
• neither the inside nor outside

The amount of a substance that is in contact iwth another substances is called 

• surface area
• particle size
• temperature
• crushing

Molecules move faster, resulting in solvent molecules colliding with the solute more frequently

• surface area
• particle size
• temperature
• crushing

Increasing the temperature of a solvent will __________ the rate at which all solid solutes dissolve

• Increase 
• Decrease
• Increase then decrease
• decrease then increase

Which sample of sugar dissolves the fastest

• sugar cubes in cold tea
• granulated sugar in cold tea
• sugar cubes in hot tea
• granulated sugar in hot tea

The rate of solubilitiy of a solid in a liquid can be increased by 

• Stirring the liquid
• Using larger solute particles
• cooling the liquid
• decreasing the surface area of the solid

How fast something dissoves is called the 

• solubility of a substance
• mount of solute 
• Strength of the solution
• Rate of dissolving
