How much heat would it take to melt 2000 kg of snow that started at -10 degrees Celsius? specific heat of snow is 2100 J/kgC
heat of fusion is 3.34 x 10^5 J/kg
treat this a two questions:
one to heat the snow to its melting point, the other to melt the ice
an explanation would be appreciated :)
if you answer bs for points ill report and cry >:/

Asheet of steel 1.5 mm thick has nitrogen atmospheres on both sides at 1200oc and is permitted to achieve a steady-state diffusion condition. the diffusion coefficient for nitrogen in steel at this temperature is 6 x 10- 11 m2 /s, and the diffusion flux is found to be 1.2 x 10-7 kg/m2 -s. also, it is known that the concentration of nitrogen in the steel at the high-pressure surface is 4 kg/m3 . how far into the sheet from this high-pressure side will the concentration be 2.0 kg/m3 ? assume a linear concentration profile.
