- A: You have included too many questions in your posting. I would recommend breaking it into many questions and repostingI’ll show you the first one.It takes 3 steps to accomplish this problem..Step 1 = melt the ice using Q = m*Lf = 0.050kg*3.34×10^5J/kg = 16700JStep 2 raise the temp from 0 to 100 using m*c*deltaT = 0.050kg*4186J/kg*(100) = 20930JStep 3 vaporize 5 g of water usin Q = m*Lv = 0.005kg*2.26×10^6J/kg = 11300JSo the total energy = 16700 + 20930 + 11300 = 48930J

- A: I’ll do the first one for you, but your expectations of poeple are way too high! You should never lay this much of your own work on others!1. KE = 0.5mv^2= 0.5(1500kg)(5.0m/s)^2= 18,750J18,750J = 18,750J(0.239cal / 1.00J)= 4481.25calSo A for 1.Good luck.
