MCQ
Q.
When ice is converted into water, then __________.
Correct Answer: A
The correct answer is Heat is absorbed.
Key Points
- When ice is converted into water heat is absorbed by the ice, so the molecules of ice increase their energy and convert into water. Hence option A is correct.
Additional Information- The conversion of ice into water is an example of melting. If you took out the ice cubes from the freezer and placed them in a warm room, the ice would absorb energy from the warmer air around them. This absorbed energy would facilitate them to overcome the force of attraction holding them together, enabling them to slip out of the fixed position that they held as ice. The process in which solids change to a liquid is called melting. The melting point is the temperature at which a solid changes to a liquid.
- The static water is converted to ice It means when the water is converted into ice its potential energy decreases.
- If we compare the kinetic and potential energy of the water vapor, water and ice then water vapor has the most kinetic as well as potential energy as compared to water and ice.
- This is because the particle of water vapor is free to move and they can move more vigorously. Please note that kinetic energy is associated with moving objects whereas potential energy is associated with a static object.
