These are experimental pencasts using a livescribe pulse pen. This material is under development and I am not happy with the way they are currently posted. Be sure to turn your speakers on.

Note: Click on the to open the mathcast and to close it. PV=nRT, solve for R E=hc/lambda, solve for lambda Q=mc(TF-TI), solve for TF mCcC(TF-TC) = -mHcH(TF-TH), solve for TH mCcC(TF-TC) = -mHcH(TF-TH), solve for TF E = R[(1/ni2)- (1/nf2)], solve for nf
