Yeah, that's what we did. We used a variety of temps from -17c to about 80c and just estimated what 0K would be

An ideal gas is supposed to be composed of randomly moving non interacting particles. I read that air can be treated as an ideal gas at standard temp and pressure. Would it ruin the percent error due its deviations from ideal gas behavior when we lower the temperature and pressure?

I just performed a lab in my physics class, and there are a few conceptual questions that I am having trouble with. The lab was simple. We took a constant volume sphere made of Stainless steel and filled with air. We changed the temperature of the water it was into record the corresponding...

thank you very much :) Also, if i need to answer this problem to the correct number of sig figs, how many sig figs would that be?

I looked it up and it said the ocean's volume was 7.14x10^8Km^3 so i multiplied this x 1027kg/m^3(density of sea water) then x 1000m^3/1km^3

I think it would take more. I'm still not sure how to work in a conversion factor though. I worked the problem up to 0.396 Btu/lb*C (which i think is correct)

so for the first problem, i got it to 0.396 Btu/lb*C From that point I am still not understanding how to implement that equation to get it to F and for the second problem I know i need to use Q=mcDeltaT Q=(7.33x10^14kg kg of water)(3850 J/kg*C)(0.56*c) Is that right prior to...

have two specific heat questions that I am having trouble with. Though i thought this was a chemistry topic, we are learning it in my physics class as well 1. The specific heat of aluminum is 0.22 cal/g *C What is the specific heat in Btu/lb*F The Fahrenheit is the part that I...
