Answer to Question #197971 in General Chemistry for Riane

Question

An equal amount of ice cubes and boiling water was made to come in contact with each other and was left undisturbed in a room. What will be the approximate temperature of the mixture after 24 hours?

a. 75°C

b. 4°C

c. 50°C

d. 25°C

Answer 1

From, Heat lost = Heat gained

m_wc_w∆T_w = m_ic_i∆T_i

m_w = m_i

c_w = c_i

$\therefore$ ∆T_w = ∆T_i

(100°C - T_m) = (T_m - 0°C)

2T_m = 100°C

T_m = 50°C
