Sodium Hydroxide Specific Heat Capacity



Specific heat for some common liquids and fluids - acetone, oil, paraffin, water and many more

  1. Equal volumes, 50.0 mL, of 3.0 M hydrochloric acid and 3.0 M sodium hydroxide solutions having an initial temperature of 20.0°C react in a calorimeter. The resultant solution records a temperature of 40.0°C. The heat gained by the resultant solution can be calculated using.
  2. Determination of Heat Capacity. Introduction: The purpose of this experiment was to determine the heat capacity of an adiabatic calorimeter. An adiabatic calorimeter is an apparatus used to measure heat changes for experiments done at constant pressure. Heat capacity is the amount of heat required to raise the heat of a system one degree.

The specific heat for some commonly used liquids and fluids is given in the table below.

Heating Energy

The energy required to heat a product can be calculated as

q = cp m dt (1)

where

q = heat required (kJ)

cp = specific heat (kJ/kg K, kJ/kg oC)

dt = temperature difference (K, oC)

Example - Required Heat to increase Temperature i Water

10 kg of water is heated from 20 oC to 100 oC - a temperature difference 80 oC (K). The heat required can be calculated as

q = (4.19 kJ/kg K) (10 kg) (80 oC)

= 3352 kJ
