when 500 grams of ice at -2 °C is placed in 1000 grams of liquid water at 4 °C. the final temperature is 10 °C.
The specific heat capacity expression is given as :
Q = mc ΔT
the heat lost = the heat gained
mc ΔT = mc ΔT
500 × ( T + 2 ) = 1000 × ( T- 4)
500 T + 1000 = 1000 T - 4000
500 T = 5000
T = 10 °C
Thus, when 500 grams of ice at -2 °C is placed in 1000 grams of liquid water at 4 °C. the final temperature is 10 °C.
