Endothermic and Exothermic Review

Front

What is an exothermic reaction?

Back

A reaction that releases heat to its surroundings, causing the temperature of the immediate environment to increase.

Front

What is an endothermic reaction?

Back

A reaction that absorbs heat from its surroundings, causing the temperature of the immediate environment to decrease.

Front

Give an example of an exothermic reaction.

Back

Combustion of fuels, such as burning wood or fireworks.

Front

Give an example of an endothermic reaction.

Back

Photosynthesis in plants, where they absorb sunlight to convert carbon dioxide and water into glucose.

Front

What does 'exo' mean?

Front

How do you identify an exothermic reaction in terms of temperature change?

Back

The reaction feels warm or hot to the touch.

Front

How do you identify an endothermic reaction in terms of temperature change?

Back

The reaction feels cool to the touch.

Front

What is the role of energy in chemical reactions?

Back

Energy is either absorbed or released during chemical reactions, determining whether they are endothermic or exothermic.

Front

What is the significance of activation energy in reactions?

Back

Activation energy is the minimum energy required for a reaction to occur, regardless of whether it is endothermic or exothermic.
