Transcribed Image Text:**Question:**
The rate of heat loss ________ when a person is submerged in cold water because water has much greater thermal conductivity than air at the same temperature.
**Options:**
- Decreases
- Stays the same
- Increases
- None of the above
**Explanation:**
This question is designed to help students understand the concept of thermal conductivity. Water, having higher thermal conductivity compared to air, leads to increased heat loss when a person is submerged. This occurs because water transfers heat away from the body more efficiently than air, especially at the same temperature. Students should recognize that the correct answer is likely to be "Increases" given this context.
Expert Solution

Step 1
Heat loss is mainly to the evaporation of the sweating reproduce on the land. But it occurs differently once we are placed in water.
