Determine the final temperature of a mixture containing water, ice, and a calorimeter with given electrical heating parameters.

Here's the solution to determine the final temperature of the mixture:

Given Data:

• Mass of calorimeter, $m_c = 1.5 \text{ kg}$
• Current, $I = 0.4 \text{ A}$
• Voltage, $V = 1.6 \text{ V}$
• Mass of water, $m_w = 4.0 \text{ kg}$
• Initial temperature of water and calorimeter, $T_{initial, w+c} = 30^\circ\text{C}$
• Mass of ice, $m_i = 2.0 \text{ kg}$
• Initial temperature of ice, $T_{initial, i} =
