1. Heat stroke occurs because of overexposure to heat and dehydration that leads to inability to maintain equilibrium. Chidren are more susceptible to heat exhaustion and stroke as heat tolerance is mainly affected by body size.
The others reasons include greater surface are to body mass ratio, and lower rate of sweating.
Option is ( D) children do not sweat as much.
Add Answer to:
Why

b. 7. Why does it take more heat to increase the temperature of diatomie gas vs. monoatomic gas (why the heat capacity of diatomic gasses are larger)? Choose the most correct statement: Monoatomic gas Diatomic gas a. Diatomic gasses are always heavier than monoatomic gasses, so it takes more energy to increase its temperature. b. Diatomic gasses have rotational motion that monoatomic gasses do not have. More energy is needed to make the diatomic gasses to spin faster. . The...
