Hey I would like some assistance; with bii)

14 a Define the terms specific latent of fusion and specific latent heat of vaporisation. [3] b 25 g of ice at -12 C is added to a polystyrene cup containing 180g of water at 26 .C. Calculate: i the amount of thermal energy required to convert the ice to water at 0 .C [3] ii the final temperature of the water. [3] [specific heat capacity of water = 4.2 x 103 J kg K-1, specific heat capacity of ice = 2.1 x 103 J kg K-1, specific latent heat of fusion of ice = 3.3 x 105j kg 1.]
