Answer

1.6 , \text{V}$

Step 1: Identify the given values for part 5a.

Voltage of heater $V = 1.6 \, \text{V}$
Current through heater $I = 0.1 \, \text{A}$
Time duration $t = 15 \, min = 15 \times 60 = 900 \, \text{s}$
Mass of copper calorimeter $m_c = 1.5 \, \text{kg}$
Mass of water in calorimeter $m_w = 10 \, \text{kg}$
Initial temperature of calorimeter and water $T_1 = 30^\circ \text{C}$
Mass of ice added
