You have collected exactly 2800 aluminum cans for recycling, each with a mass of 14.1 gHow much energy is needed to melt them if their initial temperature is 25.3?C? Assume the specific heat, the latent heat and the melting point of aluminum are 899 J/kg · ?C, 3.97 × 10^5 J/kg and 660.4?C respectively(Answer in units of J.)Round your answer please, thanks
if you know anyone with kids ask them if they need a babysitter! :)
Find some friends or find some concerts that are around youOr maybe learn to do something to do.
I hung out with my friends mostly when I was 14There's not much you can do job or volunteer-wise or anything when you're 14.
Well you have a computer and I would assume a word processorSo write a novel about a 14 y/o who starts out in the tinniest town in the world and who ends up being the overlord of the galaxyThen box it up and sent it to a publishing companyThe worst thing that will happen will be you will have a rejection slip from a big publisherHow cool is thatThe best thing that can happen is that they can send you all the money in the worldHell look at Stephen King.
The total mass 28000.0141kg 39.48kg The energy (Q) required can be calculated in 2 steps 1) Raise the temp of Al from 25.3oC to 660.4oC using Q mcΔT 39.48kg899J/kg-oC(660.4 -25.3) 2.25x10^7J 2) Melt the Al using Q mLf 39.483.97x10^5J/kg 1.567x10^7J So the total Q needed 2.25x10^7J + 1.567x10^7J 3.82x10^7J
