(a)

Interpretation Introduction

Interpretation:

The energy released from combustion of coal in kJ is to be calculated.

Concept introduction:

Internal energy of a process is the summation of the kinetic energy and potential energy associated with the process. In case of reaction, the change in internal energy (ΔE) is the difference of the energy of the product and reactant.

The expression to convert kJ into J is:

1kJ=1000J

(b)

Interpretation Introduction

Interpretation:

The energy released from combustion of coal in kcal is to be calculated.

Concept introduction:

Internal energy of a process is the summation of the kinetic energy and potential energy associated with the process. In case of reaction, the change in internal energy (ΔE) is the difference of the energy of the product and reactant.

The expression to convert kcal into kJ is:

1kcal=4.184kJ

(c)

Interpretation Introduction

The energy released from combustion of coal in Btu is to be calculated.

Concept introduction:

Internal energy of a process is the summation of the kinetic energy and potential energy associated with the process. In case of reaction, the change in internal energy (ΔE) is the difference of the energy of the product and reactant.

The expression to convert Btu into kJ is:

1Btu=1.055kJ
