Question

Part 1. Show sample calculation of calorimeter constant, Kcal using dau sure to include formulas, sample data, units, and sig figs for credit constant, Kaal using data from Trial #1. Make

Answer 1

Calorimeter constant is a constant that relates to the heat capacity of the calorimeter. It is calculated using the below equation:

ΔΗ CAT AH = Changeinenthalpyin joules AT = Change intemperature in kelvinor celsius

The heat capacity of the calorimeter, Ccal, can also determine by dividing qcal by the temperature change.

Where qcal is the heat gained by the calorimeter, which is determined by :

Ical = 9ct - Ecoid ATing=-9.4 °C AT coa =7.4 °C Ingr = mspecific heat of water x AT70 9x=18x(4.186 CX(-94°C) por=-39.35J 9coid =, specific heat of water x Alcoia Pesia=18x{4.186 x+c )*(7.4°C) g*°C coa = 30.97J

Heat gained by the calorimeter:

Ical = 9not - 9 cod =-(-39.35J)-(+30.971) = 8.38J

Heat capacity of the calorimeter or calorimeter constant Ccal:
