endothermic vs exothermic

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs heat from its surroundings, resulting in a decrease in temperature of the immediate environment.

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases heat to its surroundings, resulting in an increase in temperature of the immediate environment.

Front

Give an example of an endothermic process.

Back

Melting ice is an example of an endothermic process, as it absorbs heat from the surroundings to change from solid to liquid.

Front

Give an example of an exothermic process.

Back

Combustion of fuels, such as burning wood or gasoline, is an example of an exothermic process, as it releases heat.

Front

What happens to temperature during an endothermic reaction?

Back

The temperature of the surroundings decreases during an endothermic reaction because heat is absorbed.

Front

What happens to temperature during an exothermic reaction?

Back

The temperature of the surroundings increases during an exothermic reaction because heat is released.

Front

What is the role of heat in endothermic reactions?

Back

In endothermic reactions, heat is absorbed from the surroundings to facilitate the reaction.

Front

What is the role of heat in exothermic reactions?

Back

In exothermic reactions, heat is released into the surroundings as a byproduct of the reaction.

Front

How does an ice pack work in terms of thermodynamics?

Back

An ice pack works by absorbing heat from the body (endothermic process), which helps to reduce swelling and pain.

Front

What is the significance of understanding endothermic and exothermic reactions in real life?

Back

Understanding these reactions is crucial for applications in chemistry, biology, environmental science, and engineering, as they explain energy transfer in various processes.
