Chapter 3, Problem 3.5NP

Interpretation Introduction

Interpretation:

The final temperature needs to be determined, when 34.05 g of ice at 273 K is dropped into 185 g of liquid water at 310 K.

Concept Introduction:

Chemical reactions in general involve exchange of heat between the system (reactants and products) and the surroundings. The heat (q) absorbed or evolved in order to change the temperature (ΔT) of n moles of a substance of heat capacity c is given as: $\text{q = n ×c×ΔT ------(1)}$

Enthalpy of fusion (ΔH_fus) or the latent heat of fusion is the amount of energy required to change the state of a substance from solid to liquid

  $\text{q = n ×}\Delta {\text{H}}_{\text{fus}}\text{----(2)}$
