Chapter 5, Problem 5.82P

Interpretation Introduction

(a)

Interpretation:

The amount of heat released during condensation of given steam should be calculated.

Concept Introduction:

During the phase change, heat is absorbed or released and can be calculated by below mentioned formula,

$q=m\times \text{C}\times \Delta T$

In above formula, q is the amount of heat released or absorbed, m is mass of substance (in grams), C is specific heat capacity and $\Delta T$ is difference in temperature.

Interpretation Introduction

(c)

Interpretation:

The reason behind more painful burns of steam as compared to hot water burns should be explained.

Concept Introduction:

A phase change is a change of matter from one physical state to another like solid to liquid or liquid to gas or solid to gas.
