If $100\text{ grams}$ of ice cubes at $0^\circ\text{C}$ completely melt into liquid water at $0^\circ\text{C}$, what will be the total mass of the water formed?
  1. Less than $100\text{ g}$
  2. Exactly $100\text{ g}$
  3. Greater than $100\text{ g}$
  4. $0\text{ g}$

Solution

During a change of physical state, mass is conserved, so $100\text{ g}$ of ice yields exactly $100\text{ g}$ of water.
