Assuming that negligible heat is taken from the surroundings, the temperature of water in the tumbler becomes nearly (L = 80 cal/g)(a) 31°C(b)22°C(c)19°C(d)15°C

(b)

Let the final temperature be T

Heat gained by ice = mL + m × s × (T- 0)

= 10 × 80 + 10 × 1 × T

Heat lost by water = 55 × 1 × (40 - T)

By using law of calorimetery,

800 + 10T = 55 × (40-T)

Þ T = 21.54° C = 22°C
