The character Wolverine has had his bones replaced with a high-density, high-strength metal alloy called Adamantium, which has the following properties:
A density of 8 g/cm3
A specific heat of 0.462 kJ/kg K, and
A coefficient of linear expansion of 14 x 10-6/C°.
During a certain fight, Wolverine's core body temperature increases from 38C to 40C. Now let's model one of his femur bones (thigh) as a cylinder with a radius of 1.25 cm and a length of 52 cm.
(Note: Double check your units on the questions that follow. What is the mass of one of his humerus bones?
m = ?
How much energy did the bone have to absorb in order for its temperature to have increased?
Q = ?
By how much does the length of his bone increase?
ΔL = ?
length = 52 cm
radius = 1.25 cm
volume = 2pi*r*l =408.407 cm3
now, density = 8 g/cm3
so, mass = 408.407 cm3* 8 = 3267.25 g = 3.267 Kg
Q = m*Sp * dT
where , sp is the specific heat
dT is the temperature rise
=3.267kg * 0.462 kJ/kg K * (40-38)
=3.018 KJ of energy is absorbed
for linear expansion,
so increase in length
=14 x 10-6/C°.* 0.52 m *(40-38)
= 1.456 x10-5 m increase in length of bone
=14.56 micrometer increase

The character Wolvenne (see picture) has had all of his bones replaced with a high density, high-strength metal alloy called Adamantium, which has the following properties A density of 7.90 g/cm - A specific heat of 0.470 J/g-K . A coefficient of linear expansion of 13.5 x 10-6/C" Let's consider his left femure to be a cylinder with the following properties - A radius of 1.25 cm A length of 50.0 cm - A mass of 1980 g During a...
