Chapter 7, Problem 7.34P
Interpretation Introduction

(a)

Interpretation:

Write Energy balance on the human body.

Concept introduction:

First law of Thermodynamics for a closed system.

Δu+ΔEk+ΔEp=QW

The right hand side of the equation gives the total energy transferred to the system and the left hand side gives gain in total energy of the system.

The definitions of the symbols are Δu = Change in internal energy, ΔEk = Change in kinetic energy, ΔEp = Change in potential energy, Q = Heat added to system and W = Work done by the system

Interpretation Introduction

(b)

Interpretation:

Calculate the surrounding temperature for a clothed person and for a nude person.

Concept introduction:

First law of Thermodynamics for a closed system.

Δu+ΔEk+ΔEp=QW

The right hand side of the equation gives the total energy transferred to the system and the left hand side gives gain in total energy of the system.

The definitions of the symbols are Δu = Change in internal energy, ΔEk = Change in kinetic energy, ΔEp = Change in potential energy, Q = Heat added to system and W = Work done by the system

Interpretation Introduction

(c)

Interpretation:

Explain why hot air is more comfortable than hot water.

Concept introduction:

First law of Thermodynamics for a closed system.

Δu+ΔEk+ΔEp=QW

The right hand side of the equation gives the total energy transferred to the system and the left hand side gives gain in total energy of the system.

The definitions of the symbols are Δu = Change in internal energy, ΔEk = Change in kinetic energy, ΔEp = Change in potential energy, Q = Heat added to system and W = Work done by the system
