Chapter 54, Problem 1SA
What is the amount of heat necessary to change the state of a substance called?
Expert Solution & Answer
To determine
The name given to the amount of heat necessary to change the state of a substance.
Answer to Problem 1SA
The heat necessary to change the state of a substance is termed as latent heat.
Explanation of Solution
When there is a change in state of a substance that is the substance becomes liquid from solid or vapor from liquid or vice versa, a huge amount of heat is required, this heat is termed as latent heat of vaporization and this process is termed as phase change.
Phase change is quite a complex process and during this process, no change in pressure or temperature is observed.
Conclusion:
Thus, the heat necessary to change the state of a substance is termed as latent heat.
