The diagram above illustrates a conical flask containing water and ice. Which of the following is correct about the diagram?
- The water is at lower temperature than the ice
-
Energy is absorbed when the ice changes to water
- Energy is released when the ice changes to water
- The water molecules vibrate about a fixed point
The correct answer is: B
Explanation
Heat energy near the ice gets absorbed into the ice. The energy breaks the bonds of the ice, causing it to melt into liquid water. On other words, when ice melts, the energy gets absorbed into the water.
