Question
When m gm of water at 10oC is mixed with m gm of ice at 0oC, which of the following statements are false?
Options
A.The temperature of the system will be given by the equation
m × 80 + m × 1 × (T − 0) = m × 1 × (10 − T)
m × 80 + m × 1 × (T − 0) = m × 1 × (10 − T)
B.Whole of ice will melt and temperature will be more than 0oC but lesser than 10oC
C.Whole of ice will melt and temperature will be 0oC
D.Whole of ice will not melt and temperature will be 0oC
Solution
Heat required to melt ice = m × 80
Heat given by the water = m × 10 × 1 = 10m
Heat required to melt ice > Heat given by water so complete ice will not melt.
Heat given by the water = m × 10 × 1 = 10m
Heat required to melt ice > Heat given by water so complete ice will not melt.
