Quiz 13-2
1) Tf= (Mw*Tw-79.7*Mice)/(Mice+Mw)
2)

3)negative K*A*(T2-T1)/(L/1000)

4)(K*A*T)/(L/1000)= ans'
(Kcal*1000*4.187)/ans'= answer

5)((P/A)/((5.67*10^-8)*e))^1/4=T
raise the whole thing by 1/4 not jus the denominator to get T and then
T-273=answer

6) negative P=(5.67*10^-8)(e*A(T^4-Ts^4)
add 273 to both temps first, Ts is the 273 one
