Question
Chapter 12, Problem 98A
Interpretation Introduction
Interpretation:
Three Changes that require energy to occur and three changes that release energy needs to be determined.
Concept introduction:
The process which involves the release of energy is exothermic process while the process in which energy is provided is endothermic process.
Expert Solution & Answer
Explanation of Solution
When a substance goes from higher to lower energy state energy is released while when it undergoes change from lower energy state to higher it requires energy.
Thus, in the process of fusion, vaporisation and sublimation energy is required to be performed.
In the process of condensation, freezing and formation of snow energy is released.
Conclusion
On the change of state of a substance either energy is released or absorbed.
