Chapter 10, Problem 17QAP
Interpretation Introduction

(a)

Interpretation:

ΔE should be calculated when q = + 65 kJ and w = -22 kJ

Concept Introduction:

The change in internal energy is equal to sum of heat and work done.

The mathematical expression is given as:

ΔE =q+w

Where, q = heat and w = work done.

If heat is released from the system, q is negative and if heat is absorbed by the system, q is positive.

If work is done on the system, w is positive and if work is done by the system, w is negative.

Interpretation Introduction

(b)

Interpretation:

ΔE should be calculated when q = + 200. kJ and w = -73 kJ

Concept Introduction:

The change in internal energy is equal to sum of heat and work done.

The mathematical expression is given as:

ΔE =q+w

Where, q = heat and w = work done.

If heat is released from the system, q is negative and if heat is absorbed by the system, q is positive.

If work is done on the system, w is positive and if work is done by the system, w is negative.

Interpretation Introduction

(c)

Interpretation:

ΔE should be calculated when q = -18 kJ and w = -40. kJ

Concept Introduction:

The change in internal energy is equal to sum of heat and work done.

The mathematical expression is given as:

ΔE =q+w

Where, q = heat and w = work done.

If heat is released from the system, q is negative and if heat is absorbed by the system, q is positive.

If work is done on the system, w is positive and if work is done by the system, w is negative.
