Answer

When the bonds between water molecules are broken at a constant temperature, energy has been **added, no change in** their speed.<br /><br />Here's why:<br /><br />* **Breaking bonds requires energy:** Think of it like pulling magnets apart. It takes effort (energy) to separate them. Similarly, breaking the bonds between water molecules requires an input of energy.<br /><br />* **Constant temperature means no change in kinetic energy:** Temperature is a measure of the average kinetic energy (energy of motion) of the molecules. If the temperature remains constant, the average speed of the molecules also remains constant. The added energy goes into breaking the bonds, not increasing the kinetic energy of the molecules. This added energy is called potential energy.<br />
