 In this assignment, you will be playing an immersive online learning simulation.

                Below you can read the main learning outcomes and techniques you'll practice, as well as a brief introduction and storyline to the simulation.

                Once you are ready, you can start the simulation by pressing the simulation launch button/link.

       
                Learning Objectives

At the end of this simulation, you will be able to…

Define the core thermodynamics concepts of entropy, enthalpy, and free Gibbs energy, and their units

Explain the first and second laws of thermodynamics

Understand and apply the concept of reaction spontaneity

Explain the differences between the enthalpy of combustion, and enthalpy of formation

Understand the relationship between internal energy and enthalpy

Present Hess’s law in connection with performing enthalpy change calculations

Present the concepts of exothermic and endothermic reactions

    
                Techniques:

Calorimetry

  
            About this Learning Simulation

Energy is one of the great subject matters of our time, but what is energy actually? In this simulation you will learn the fundamental thermodynamic concepts of enthalpy, entropy and Gibbs free energy. You will also determine the internal energy of a chemical compound by using bomb calorimetry, and you’ll even travel inside the calorimeter to see it in action!

The challenge of storing energy

What is the best way to store energy? There is no simple answer, but in this simulation, you will be encouraged to give it some thought while learning about the very nature of energy and how it connects to chemical reactions. You will assess whether the gasoline component octane is a suitable chemical for energy storage by using a bomb calorimeter.

The fundamental concepts of thermodynamics

The first and second laws of thermodynamics and the core concepts of enthalpy, entropy and Gibbs free energy are introduced in this simulation. You can play around with the energy levels of reactants and products on a virtual energy surface to learn about endothermic and exothermic reactions. The concept of reaction spontaneity is linked to the concept of Gibbs free energy and its temperature dependence is explored in an interactive game. You will have access to a state-of-the-art bomb calorimeter and can travel inside to see it in action, in order to really be able to understand how it works. From here the concept of chemical bond energy is linked to the thermodynamic calculations of enthalpy on the calorimeter output.

Combine theory and practice

Throughout the simulation you will combine the fundamental teachings of thermodynamics with the experimental results from the calorimeter.

Will you be able to suggest a solution for the energy storage challenge?
