Chapter 4.8, Problem 4.10PSP

Interpretation Introduction

Interpretation:

The highest temperature attained when given solutions are mixed in coffee cup calorimeter has to be determined using the given conditions from Problem-Solving Example 4.10.

Concept Introduction:

Coffee cup calorimeter: It is constant pressure calorimeter. It contains two coffee cups, cork lid, temperature probe and stirrer. The temperature change is used to calculate $q_P\text{ and }{\Delta }_{\text{r}}\text{H}$ since, there will no energy transfer from in and out of calorimeter.

The energy transferred is determined by formula ${\text{- c}}_{\text{water}}{\text{× m}}_{\text{water}}{\text{×ΔT}}_{\text{water}}$.

Here,

$c_{water}\text{ =}$ specific heat capacity of water.

${\text{m}}_{water}\text{ =}$ water mass

$\Delta T_{water}=$ temperature change of water.
