Under the given scenario, the heat released by steam equals the heat absorbed by ice. What is the value of thermal conductivity (K)?

1. K = 1.24 J/m/s/°C
2. K = 1.5 J/m/s/°C
3. K = 1.0 J/m/s/°C
4. K = 2.0 J/m/s/°C

Correct answer: K = 1.5 J/m/s/°C

Solution

The problem involves heat transfer, and the condition equates the heat lost by steam to the heat gained by ice. Based on typical thermal conductivity values and the given options, K = 1.5 J/m/s/°C is the most reasonable choice.
