Question
The mass of the ice cube is 11.0 g and its initial temperature is -14.9 C. The water resulting from the melted ice reaches the temperature of your skin, 29.0 C. How much heat is absorbed by the ice cube and resulting water. Assume all the water remains in your hand. The mass of the ice cube is 11.0 g and its initial temperature is -14.9 C. The water resulting from the melted ice reaches the temperature of your skin, 29.0 C. How much heat is absorbed by the ice cube and resulting water. Assume all the water remains in your hand.Explanation / Answer
Q= ms delta T
Given T1 = -14.9 C
T2 = 29 C
T2- T1 = 29 - 14.9 = 14.1 degree C
mass of the ice cube = 11.0 g
specific heat of
Q= MC ice (delta T)+mLf = (0.011kg)[(2.090 j/Kg.degree C) (14.1 degree C)+ 3.33 x 10^5 j/Kg]
Q= MC ice (delta T ) +mLf = 3663.32 J
