A 67.3-kg man has a fever, and his average body temperature is 39.3oC. What mass of ice, initially at 0.0oC, should he consume in order to bring his average body temperature down to 36.3oC? Assume no heat loss to the surroundings, and neglect complexities introduced by metabolism
kg
Homework Answers
cbody = specific heat of body = 3470
mbody = mass of body = 67.3 kg
L = latent heat of ice = 334 J /kg
cwater = specific heat of water = 4186
m = mass of ice
Heat gained by ice = heat lost by man
mL + m cwater (36.3 - 0 ) = mbody cbody (39.3 - 36.3)
m(334000) + m (4186) (36.7 - 0 ) = (67.3)(3470) (39.3 - 36.3)
m = 1.436 kg

A 1.88 -m ( 6 ft 2 in. ) man has a mass of 81 kg, a body surface area of 1.8 m 2 , and a skin temperature of 35.7 ∘ C. Normally, 80 % of the food calories he consumes go to heat; the rest goes to mechanical energy. His emissivity e is 1 because his body radiates almost entirely nonvisible infrared energy, which is not affected by skin pigment. (Careful! His body at 35.7 ∘ C radiates...

A 70-kg man canoeing on the White River tips his canoe and ends up in the river. When he is rescued from the cold water, his body temperature has fallen to 33°C (91.4°F). He is placed in 50 kg of warm bath water at 41 °C (105.8°F). What is the final temperature of the man and the water? The specific heat (c) of a human body is 3500 J/kg °C, and the specific heat of water is 4190 J/kg °C.

In a container of negligible mass, 0.200 kg of ice at an initial temperature of -36.0 ∘C is mixed with a mass m of water that has an initial temperature of 80.0∘C. No heat is lost to the surroundings. If the final temperature of the system is 30.0 ∘C, what is the mass m of the water that was initially at 80.0∘C?

The body is designed to maintain a constant temperature of about 37 °C under normal healthy re is lower (say 25 °C), there must be a continuous heat 1 from the body. This heat loss can be modeled as oss A(T-T) T is the body temperature, Ta is the room temperature, A is the body surface area (assume 1.73 m2). The heat transfer coefficient h is 4.09 W/(m2 "C). Note that Qross <0. Because of the continuous heat loss, the...

Jake weighs 70 kg and has a core body temperature of 37 ° C when he begins steady state exercise at a VO2 of 2.5 L O2/min (12.5 kcal/min). His gross mechanical efficiency is 15%, and his sweat rate is 10 mL/min. Assume that all sweat produced evaporates and that 10% of heat produced is lost through radiative, conductive, and convective heat losses combined. After 45 minutes of exercising at this VO2, how much will his body temperature increase? (5...

The average human produces about 15 g of sweat per minute during intense activities. a. If a jogger runs for 30 mins and evaporates all of the sweat he produces after his run, how much heat was transferred from his body to the sweat? Assume the jogger is always seating, the sweat’s initial temperature is 37°C, and that sweat has the same specific heat and latent heat as water. b. A heat stroke occurs when a human’s body temperature reaches...
