determine the resulting temperature when 1kg of ice is mixed with 900 g of water at 50 degree celcius???

Question

anonymous · Answer

Let the final temperature of the water be x
and imagine that there is sufficient energy to melt all the ice so that x > 0
This can be confirmed or otherwise shortly.

The ice requires 334000 J to melt
plus 4160 * x to raise the temperature to x

This energy comes from cooling the remainder of the water
mass * temperature change * specific heat
9 * (50 -x ) * 4160


hence 334000 + 4160 * x = 9 * ( 50 -x ) * 4160

Now solve
334000 + 4160 x = 450 * 4160 - 9x * 4160
