When a question uses charles law, and wants you to find the temperature, but asks for it in Celsius temperature,
((it gives the volume in liters and one temperature in celsius))
Do I convert the temperature to Kelvin to do the calculations and then subtract 273.15 to get Celsius, or do I just use the temperature it gives in Celsius to do the calculations? Because i tried it both ways and got a different answer.
Here is the question:
Use charles law to find T1:
V1= 146 L V2= 89 L T2= 132degrees C
answer in units of degrees C.
Charle's law is V1T2=V2T1
I converted T2 to K (405) and then i just subtracted 273.15 at the end to get the temperature of 391.232 C
If i do it with Celsius from the beginning, i get 216.539 C.
Which is correct?

first i have to identify the inner function u = g(x) and the outer function y = f(u).
then i need find the derivative dy/dx.
i already know the answer is 10(x^2 + 4x + 6)^4(x + 2).

I really want to understand this problem and im not being lazy or anything. any help is appreciated.

In college, I've seen many laws in math and science. I do not recall hearing of a "Law of Probability." The realm of probability has its own set of laws, and perhaps when a lay person uses that phrase, he means "by virtue of probability alone."

One example of the phrase being used is, "The Law of Probability makes the Big Bang an impossible event." I suspect the speaker is speaking on behalf of ignorance, since I'm not aware of this Law of Probability, but I thought I'd check with others before utterly dismissing it.

I need to know the best earthquake design for a rectangular building split into 4 levels with weighted "floor" plates in between for a Tech class. Basically, I'm asking for the best design for structural supports/ braces on the sides. Thanks!
