Some qualities are represented in capitals and some lowercase to create less confusion in which symbol represents what. For example, T represents temperature while t represents time. s represents seconds while S represents entropy. K represents Kelvin while k represents thermal conductivity.JoeyC wrote:Whoops, didn't see the second question.
Why are some qualities represented by capital letters and others lowercase. Give 3 examples of each.
Code: Select all

Yeah that's the correct answer. I should of said what the volume expansion coefficient was for steel, because it is different depending on the composition.Steuben42 wrote:First time answering, so please let me know if there's anything I'm doing wrong.[math]\Delta V = 3\Alpha V_0\Delta T[/math] I have it in my notes that the α of steel is 13x10[sup]-6[/sup] C...

While fairly accurate for certain gases, there are some that diverge slightly from predicted behavior according to the Ideal Gas Law.
1) Under what conditions is the Ideal Gas Law most accurate?
2) What is the equation that adjusts for these inaccuracies, and what are the modifications it makes to the Ideal Gas Law?
1) High temperature and volume, low pressure
2) The van der Waals equation: it adjusts the pressure and volume to account for attractive forces using two additional gas variables.
Looks all good to me, your turn!UTF-8 U+6211 U+662F wrote:Steuben42 wrote:Neat, let's see what I've got...
