Concept explainers
Interpretation:The correct choice regarding the turning of water into ice needs to be picked up.
Concept introduction: The process in which transfer of heat energy from system to surrounding takes place is termed as exothermic process and the process in which flow of energy from surrounding to system occur is known as endothermic process.
Answer to Problem 62A
The correct choice is c.
Explanation of Solution
In conversion of water to ice, the molecules of water lose energy which causes the slower movement of molecules. The molecules come closer and results close packing and forms ice. As the release of energy takes place to the surroundings, the process of conversion of water into ice is an exothermic process. So, correct choice is c.
In the process of conversion of water to ice, energy is released. So, the choice a,b, d and e are incorrect.
