Question

Body heat is lost underwater at a rate of ______ than in air?

1) 10 times slower
2) 50 times faster
3) 25 to 30 times faster
4) same

Answer 1

Body heat is lost underwater at a rate of 25 to 30 times faster than in air because water's higher thermal conductivity facilitates heat transfer more efficiently than air.

Body heat is lost underwater at a rate much faster than in air. The correct answer is 25 to 30 times faster. This is due to the fact that water has a much higher thermal conductivity than air, which allows heat to be transferred away from the body more rapidly. In fact, water is approximately 775 times as dense as air, which significantly affects heat transfer rates.
