Physics Classroom is making strides to make our site accessible to everyone. Our site contains 6 navigation areas. The Primary, Secondary, and Page Level navigations have a screen reader version of their nav structure that allows using the left and right keys to navigate sibling navigation items, and up or down keys to navigate parent or child navigation items. The others can be navigated using tabs. The Primary Navigation handles the first 2 levels of site pages. The Secondary (which is not always available) handles the 3rd and 4th level of structure. The Page level navigation allows you to navigate the current page's headings quickly. The Header Navigation contains the Light/Dark Mode toggle, Search, Notifications and account login. The Breadcrumb Navigation contains the breadcrumb of the current page. If the current page has a breadcrumb, you can get to it by skipping to the content and tabbing in reverse (shift plus tab). The Footer Navigation contains links such as Privacy, Contact, about and terms. Some resources contain an Audio Player that can be activated by holding down the T key for 3 seconds, and then using K to pause and resume. While not every area of Physics Classroom is usable purely from keyboard and screen reader, we are committed to continue work on making this possible. If you have questions or need additional help, please use this link to contact us.

Home Concept Builders Thermochemistry

Concept Builders - Thermal Chemistry and Thermodynamics

Let's turn up the heat on learning with these Concept Builders as you learn about Entropy, Heat, explosive thermochemical equations, and more.

Activities

Measuring the Quantity of Heat

🞋︎ Learning Goal: To use the equation Q = m•C•∆T to relate the heat released to the surroundings to the mass and temperature change of the surroundings and to the enthalpy change of the system.

Which One Doesn't Belong? - Energy and Chemical Reactions

🞋︎ Learning Goal: To interpret various representations of a thermochemical reaction and to identify which one is not consistent with the others.

Enthalpy Change

🞋︎ Learning Goal: To use calorimetry data and the amount of reactant to determine the enthalpy change for a stated reaction and to include the energy term on the proper side of a thermochemical equation.

Thermal Stoichiometry

🞋︎ Learning Goal: To use a thermochemical equation to relate the mass and the moles of reactant to the amount of energy released in a combustion reaction.

Hess's Law

🞋︎ Learning Goal: To apply Hess’s Law in order to determine the ∆H of a reaction if given the ∆H of two or more related reactions.

Heat of Formation

🞋︎ Learning Goal: To identify the meaning of heat of formation and to use heats of formation values for reactants and products to determine the enthalpy change of a reaction.
