Rate of Dissolving

Front

What is the rate of dissolving?

Back

The rate of dissolving refers to how quickly a solute (like sugar or salt) dissolves in a solvent (like water). It can be affected by factors such as temperature, stirring, and the size of the solute particles.

Front

Which dissolves faster: sugar in hot water or sugar in cold water?

Back

Sugar dissolves faster in hot water than in cold water.

Front

How does stirring affect the rate of dissolving?

Back

Stirring increases the rate of dissolving because it helps distribute the solute particles throughout the solvent, allowing them to interact more quickly.

Front

What happens to the rate of dissolving when the solute is in larger chunks?

Back

Larger chunks of solute dissolve slower than smaller particles because there is less surface area exposed to the solvent.

Front

What is an example of a solute?

Back

Sugar is an example of a solute when it is dissolved in water.

Front

What is an example of a solvent?

Back

Water is an example of a solvent when it dissolves substances like sugar or salt.

Front

What is the effect of temperature on the rate of dissolving?

Back

Generally, increasing the temperature of the solvent increases the rate of dissolving.

Front

What is the relationship between stirring and the rate of dissolving?

Back

More frequent stirring increases the rate of dissolving by promoting interaction between solute and solvent.

Front

Which would dissolve slower: Kool-aid powder not stirred or Kool-aid powder stirred?

Back

Kool-aid powder not stirred would dissolve slower than Kool-aid powder that is stirred.

Front

What is the effect of particle size on the rate of dissolving?

Back

Smaller particles dissolve faster than larger particles due to increased surface area.
