Chapter 10.7, Problem 10.52QAP

Interpretation Introduction

Interpretation:

Interpret amount of heat in kJ when 18 g of steam at 100 C⁰ cools to body temperature of 37 C⁰.

Concept Introduction:

Heat for changing the state of water from ice can be determined as:

  ${\text{Q}}_{\text{1}}\text{= m s dT}$

Heat required for changing the state of ice from solid to liquid.

  ${\text{Q}}_{\text{2}}\text{= m L}$

Where, m is mass of ice or water

S is specific heat of water

dT is the change in temperature

and L is latent heat.
