Exploring the Interplay of Energy and Chemistry

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.
