100 g of water is supercooled to -10^(@)...

100 g of water is supercooled to `-10^(@)C`. At this point, due to some disturbance mechanised or otherwise some of it suddenly freezes to ice. What will be the temperature of the resultant mixture and how much mass would freeze ? `[S_(w) = 1 cal//g//^(@)C and L_("Fusion")^(w) = 80 cal//g]`

A

`0^(@)C,12.5g`

B

`0^(@)C,2.5g`

C

`-10^(@)C,2.5g`

D

`-10^(@)C,12.5g`
