![]() ![]() This lesson calculates the entropy and Gibbs free energy for the combustion of carbon monoxide. This lesson calculates the enthalpy for the combustion of carbon monoxide. Lesson 7 ( Heat Capacity ) computes and compares heat capacities of ideal and real gases. ![]() Lesson 6 ( Boltzmann Distribution ) introduces the Boltzmann distribution for vibrational motion. Lesson 5 ( Maxwell-Boltzmann Distribution ) investigates the Maxwell-Boltzmann distribution of molecular speeds in ideal gases. Lesson 4 ( Thermodynamics of Combustion ) uses the same ideas introduced in Lesson 3 to calculated the thermodynamics of reaction for the combustion of methane. Lesson 3 ( Statistical Thermodynamics ) shows how internal energy, enthalpy, entropy, and Gibbs-free energy are calculated from an ideal gas diatomic using calculated electronic energies and a rigid rotor / harmonic oscillator approximation to rovibrational energies. Lessons 1 and 2 ( Enthalpy and Entropy and Free Energy ) calculate thermodynamic functions such as internal energy, enthalpy, entropy, and Gibbs free energy for the combustion of carbon monoxide. The QuantumChemistry package can be used to calculate atomic and molecular electronic properties that can then be used to approximate thermodynamic functions by calculating translational, rotational, vibrational, and electronic partition functions. As such, each lesson can be used 'as-is' or modified as desired to be used by students in a classroom setting, laboratory setting, or as an out of class guided inquiry assignment. In some cases, questions are asked of the student with the answer provided as a subsection. However, in order to show students and instructors how the calculations are set up, each lesson contains the Maple syntax and coding required to interact with the selected topic. The aim of these lessons is to provide students and/or instructors ways to interact with selected topics using the QuantumChemistry package exclusively within Maple with no need to collate multiple software packages! Lessons are written to emphasize learning objectives rather than Maple coding. This is because there was more mass of water than steel and because water has such high specific heat.Suggested Curriculum for Physics - ThermodynamicsĬomputational chemistry is a powerful tool for introducing, exploring, and applying concepts encountered throughout the chemistry curriculum. In this case, the temperature of the steel dropped significantly and the temperature of the water rose slightly. 466*10*( 90 – T final )Ĩ3.68* T final – 836.8 = 419.4 – 4.66 * T finalįinally, we re-arrange the equation above, and solve for the final temperature: Next, we enter the values provided above:Ģ0*4.184*( T final – 10 ) =. M water*C water*(T final-T water)=m steel*C steel*(T steel-T final) ![]() The mass of the steel is 10g and the mass of the water is 20g.466 J/gC and the specific heat of water is 4.184 J/gC. The initial temperature of the steel is 90C and the initial temperature of the water is 10C.Let’s take a look at a sample problem of how to calculate the final temperature of two combined objects.įor this example, we are going to say we have a hot steel ball that’s dropped into a cooler body of water. Where TF is the final temperature Final Temperature Example Problem Where q1 and q2 are the heat of both objects after combination. The following formula is used to calculate the final temperature when combining two substances of different heats. Thermal Conductivity Calculator (heat flux).Enter the mass of both objects or substances, the initial temperature of each substance, and the specific heat of each substance into the calculator to determine the final temperature of combining the two objects. ![]()
