A 1.6 V, 0.1 A heater runs for 1.5 min. Calculate the heat energy it produces. Assume no heat loss.

Step 1: Identify the given values and the principle of calorimetry.
The problem describes an energy transfer scenario where an electric heater supplies heat, and heat is exchanged between a copper calorimeter, water, and ice. The principle of calorimetry states that the total heat supplied by the heater plus the heat lost by the warmer substances equals the heat gained by the colder substances, assuming no heat loss to the surroundings.

Given values:

• Voltage of heater $V = 1.6 \, \text{V}$
• Current through heater $I = 0.1 \, \text{A}$
• Time duration $t = 1.5 \, \text{min} = 1.5 \times 60 = 90 \, \text{s}$
