### Chem and Orgo pg. 131 #5

The answer explanation for this question states that we should look to phase change and moles of gas when determining change in entropy. It said that since moles were equal on both sides, and there was no phase change, this means that entropy does not change. The answer claims there is 2 mols of gas...

### Lesson 5 warm up problems #4

Hi, maybe I just had this misconception about work the whole time, but I don't understand why the net work is 150 J as oppose to 0J for #4. I thought the formula for work was Fdcos(theta). In the problem's case, wouldn't theta be 90 degrees since the box is being lifted straight up and remaining mot...

### Physics Chapter 8 2018 edition (pg 178)

Hi, on this page, when it says refer to Figure 9 as an example of a pipe that is open on both ends, the corresponding image is of a pipe with one closed end and one open end instead. Is this an error?

### Physics Chp 4 #2 and #7 practice passage

Hi, I wanted to clarify my understanding of two questions on these passages, since the explanations were a little confusing. #2: The passage claims " thermal injury risk increases when the cooling required to maintain thermal equilibrium exceeds the heat loss to the environment. What I got from the ...

Thanks, that makes more sense. The last thing I wanted to clarify is how can we assume that we can split the net dipole in half? Thanks for all the help.

#5: Doesn't the math in the picture lead to the dipole moment being 0.52? The answer is 1.5D for the question.

#7: Thanks, that makes more sense.
