Endothermic Reactions

Endothermic reactions are chemical reactions that absorb heat from their surroundings. This means that the energy of the products is higher than the energy of the reactants. As a result, endothermic reactions feel cold to the touch because they are drawing heat from the environment.

Key Concepts:

• Endothermic reactions absorb heat from the surroundings.
• The energy of the products is higher than the energy of the reactants.
• Endothermic reactions feel cold to the touch.

Examples of Endothermic Reactions:

Some common examples of endothermic reactions include:

1. Photosynthesis
2. Evaporation of water
3. Melting of ice

Study Guide:

To understand endothermic reactions, it's important to grasp the following concepts:

1. Energy Absorption: Learn how endothermic reactions absorb heat from the surroundings and why they feel cold.
2. Energy Difference: Understand the difference in energy levels between the reactants and products in an endothermic reaction.
3. Examples: Study examples of endothermic reactions to see how they occur in everyday life and in chemical processes.

By mastering these concepts, you'll have a solid understanding of endothermic reactions and their significance in chemistry and physics.
