A copper of mass 400g is heated until it's temperature becomes 250degree celcius. It is dropped into water weighing 200g at 50 degree celcius.calculate the mass of water vapour produced.

Answer 1

figure the heat in the copper. when dropped in water, it will make steam until it(the copper) is 100C.

heat copper loses : 400*ccu*(100-250)

amount of steam: that heat above (400*Ccu*(150))=masssteam(hvaporwater)

solve for mass steam.
