A hole of 2 m × 1 m × 2m is drilled inside an ice block of 3 m × 1 m × 4m to make an ice frame. Calculate the volume of the frame.
A copper ball of mass m1, SHC x & temperature T1 is placed in ice at 00C having mass m2. If temperature of water formed & hence the mixture is T2 then calculate or derive for the expression of sp latent heat of fusion (L) of ice. [SHC of water = y]
