Crushing:
* Faster Dissolution: Crushed sugar cubes dissolve much faster than whole ones. This is because crushing increases the surface area exposed to the water. More surface area means more contact points for the water molecules to interact with and break down the sugar crystals.
Temperature:
* Hot Water: Hot water dissolves sugar much faster than cold water. This is due to the increased kinetic energy of the water molecules at higher temperatures. The molecules move faster, colliding with the sugar crystals more frequently and breaking them down more efficiently.
Combining the Factors:
* Crushed Sugar in Hot Water: This combination results in the fastest dissolution. The increased surface area from crushing and the higher kinetic energy from the hot water work together to rapidly dissolve the sugar.
* Whole Sugar in Hot Water: This combination is faster than whole sugar in cold water, but still slower than crushed sugar in hot water.
* Crushed Sugar in Cold Water: This is faster than whole sugar in cold water but slower than the combination of crushed sugar and hot water.
* Whole Sugar in Cold Water: This is the slowest combination.
In short:
* Crushed sugar dissolves faster than whole sugar.
* Hot water dissolves sugar faster than cold water.
