Determining the Molar Heat Capacity (C) of Gallium

Miles Finch

Introduction

The purpose of this experiment is to determine the molar heat capacity of Gallium using the molar heat capacity of liquid water (75.3 J/K mol). The molar heat capacity is different for different substances. The equation used is: q = nC∆T.

Procedure

Liquid water (100 moles = 1,800 g = 1,800 mL) was put into a large beaker. One mole of gallium (69.7 g) was placed in an oven set at 100C for 3 hours. The initial temperature of the water was 25C (room temperature).
