[" The fraction of ice that melts by mixing equal "],[" masses of ice at "-10^(@)C" and water at "60^(@)C" is "]

When ice melts at 1^(@)C :

When ice melts at 1^(@)C :

Equal masses of ice at 0^(@) C and water at 100^(@) C are mixed. The resultant temperature is

A thermometer has wrong calibration (of course at equal distances and the capillary is of uniform diameter). It reads the melting pont of ice as -10^(@)C . It reads 60^(@)C in place of 50^(@) . The temperature of boiling point of water on this scale is

1g of ice at 0^@ C is mixed 1 g of steam at 100^@ C . The mass of water formed is

M g of ice at 0^@C is mixed with M g of water at 10^@ c . The final temperature is

Ice melts into water it is a
