  • objective of the practical work

    These practical work sessions are intended for students in the 1st year of the Common Core, The Chemistry II practical work module consists of four manipulations:

    1.    Specific Heat and Calorific Capacity of the Calorimeter.

    2.    The Latent Heat of Fusion of Ice.

    3.    Determination of Enthalpies of Reaction.

    4.    Chemical Kinetics: AUTO-CATALYSIS.

    Each practical task is accompanied by theoretical information and questions are asked in order to check the acquisition and assimilation of knowledge. A report is submitted to the teacher within a maximum of 15 days from the date of the manipulation.

  • Manipulation 1: Specific heat and calorific capacity

    The calorific capacity C of a substance is the physical quantity that determines the amount of heat Q required to vary its temperature by a certain value ∆T. We know from experience that calorific capacity is an extensive property, in the sense that the calorific capacity of a given sample is directly proportional to its dimensions (it is faster to chauffer a glass of water than a barrel of water using the same heat source). The mass heat capacity is the calorific capacity related to the mass of the substance. It is an intensive quantity, because it depends only on the nature of the substance and not on its dimensions
