Chapter 14: Problem 20

How much heat is required to raise the body temperature of a \(50.0-\mathrm{kg}\) woman from \(37.0^{\circ} \mathrm{C}\) to $38.4^{\circ} \mathrm{C} ?$

Short Answer

Expert verified
Question: Calculate the heat required to raise the body temperature of a 50.0 kg woman from 37.0°C to 38.4°C. Assume the specific heat capacity of the human body is approximately the same as that of water (4.18 J/g°C). Answer: The heat required to raise the body temperature of a 50.0 kg woman from 37.0°C to 38.4°C is 292,600 J.

Step by step solution

01

List the given values

Mass (m) = 50.0 kg, initial temperature (T1) = 37.0°C, final temperature (T2) = 38.4°C, specific heat capacity (c) = 4.18 J/g°C
02

Calculate the temperature change

ΔT = T2 - T1 = 38.4°C - 37.0°C = 1.4°C
03

Convert mass from kg to grams

1 kg = 1000 g, so 50.0 kg = 50.0 * 1000 = 50000 g
04

Calculate the heat (Q)

Use the formula Q = mcΔT. Plug in the values: Q = (50000 g) * (4.18 J/g°C) * (1.4°C) Q = 292600 J
05

Present the final answer

The heat required to raise the body temperature of a 50.0 kg woman from 37.0°C to 38.4°C is 292,600 J.

It requires \(17.10 \mathrm{kJ}\) to melt \(1.00 \times 10^{2} \mathrm{g}\) of urethane $\left[\mathrm{CO}_{2}\left(\mathrm{NH}_{2}\right) \mathrm{C}_{2} \mathrm{H}_{5}\right]\( at \)48.7^{\circ} \mathrm{C} .$ What is the latent heat of fusion of urethane in \(\mathrm{kJ} / \mathrm{mol} ?\)
A person of surface area \(1.80 \mathrm{m}^{2}\) is lying out in the sunlight to get a tan. If the intensity of the incident sunlight is $7.00 \times 10^{2} \mathrm{W} / \mathrm{m}^{2},$ at what rate must heat be lost by the person in order to maintain a constant body temperature? (Assume the effective area of skin exposed to the Sun is \(42 \%\) of the total surface area, \(57 \%\) of the incident radiation is absorbed, and that internal metabolic processes contribute another \(90 \mathrm{W}\) for an inactive person.)
A blacksmith heats a 0.38 -kg piece of iron to \(498^{\circ} \mathrm{C}\) in his forge. After shaping it into a decorative design, he places it into a bucket of water to cool. If the available water is at \(20.0^{\circ} \mathrm{C},\) what minimum amount of water must be in the bucket to cool the iron to \(23.0^{\circ} \mathrm{C} ?\) The water in the bucket should remain in the liquid phase.
You are given \(250 \mathrm{g}\) of coffee (same specific heat as water) at \(80.0^{\circ} \mathrm{C}\) (too hot to drink). In order to cool this to $\left.60.0^{\circ} \mathrm{C}, \text { how much ice (at } 0.0^{\circ} \mathrm{C}\right)$ must be added? Ignore heat content of the cup and heat exchanges with the surroundings.
