Chapter 10, Problem 111CP

Interpretation Introduction

Interpretation:

The amount of heat required to freeze 325 g of water present at 25 C⁰ needs to be calculated.

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
