Answer:
at constant pressure, the heat flow for any process is equal to the change in the internal energy of the system plus the PV work done. Comparing the previous two equations shows that at constant pressure, the change in the enthalpy of a system is equal to the heat flow: ΔH=qp.

Answer:
A solid has definite volume and shape, a liquid has a definite volume but no definite shape, and a gas has neither a definite volume nor shape.
Explanation:
Answer:
Optimal aspect ratio = 1
Explanation:
From Chvorinov's Rule,
![T = c [\frac{volume}{surface are}]^n](https://tex.z-dn.net/?f=%20T%20%3D%20c%20%5B%5Cfrac%7Bvolume%7D%7Bsurface%20are%7D%5D%5En%20)
Where
T = solidification time
c = mold constant
For the riser to have the longest solidification time:
We have: D = h
![A = pi Dh[\frac{2pi D^2}{4}] = 1.5D^2 pi](https://tex.z-dn.net/?f=%20A%20%3D%20pi%20Dh%5B%5Cfrac%7B2pi%20D%5E2%7D%7B4%7D%5D%20%3D%201.5D%5E2%20pi)
Therefore,
To have to longest solidification time, D = h
Therefore the best aspect ratio would be,
Where is the following steps??
Pseudocodes are used as a prototype of an actual program.
The error in the pseudocode is that, the while loop in the pseudocode will run endlessly.
From the pseudocode, the first line is:
<em>Declare Boolean finished = false</em>
The while loop is created to keep running as long as <em>finished = false.</em>
So, for the while loop to end, the finished variable must be updated to true.
This action is not implemented in the pseudocode.
Hence, the error in the pseudocode is that, the while loop is an endless loop
