Study Notes
Thermochemistry: The Study of Energy in Chemistry
- Thermochemistry is the study of the relationship between chemistry and energy.
- Energy is anything that has the capacity to do work.
- Work is a force acting over a distance.
- Heat is the flow of energy caused by a difference in temperature.
- Energy can be exchanged between objects through contact, such as through collisions.
- Energy, heat, and work are different ways that an object can exchange energy with other objects.
- Energy can be thought of as a quantity an object can possess or a collection of objects.
- Heat and work are two different ways that an object can exchange energy.
- Energy can either flow out of an object or into an object.
- Thermochemistry focuses on the classification and study of energy.
- Thermochemistry is an important aspect of understanding the behavior of matter.
- Thermochemistry helps explain the relationship between energy and chemical reactions.
