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.

Calculate for the vertical cross section moment of inertia for both Orientations 1 and 2 of a 1 x 1.5 in. horizontal hollow rectangular beam with wall thickness of t = 0.0625 in.
Use the equation: I = ((bh^3)/12) - (((b-2t)(h-2t)^3)/12)
Please answer 'yes' or 'no' and 'is' or 'is not' for the following:
Consider a large 23-cm-thick stainless steel plate (k = 15.1 W/m-K) in which heat is generated uniformly at a rate of 5 x 105
W/m³. Both sides of the plate are exposed to an environment at 30°C with a heat transfer coefficient of 60 W/m²K.
The highest temperature will occur at surfaces of plate while the lowest temperature will occur at the midplane.
