Answer: B - In a hot immersion whirlpool, the temperature of water is reduced as the proportion of the body area immersed increases.

The temperature is reduced because if the patient’s core temperature is increased too rapidly, it would result in hyperthermia.

In a cold immersion whirlpool, the temperature of the water is increased as the proportion of the body area immersed increases because hypothermia occurs if the body is cooled too rapidly.
