Endothermic and Exothermic Assessment

Front

What is an endothermic reaction?

Back

A reaction that absorbs heat from its surroundings, resulting in a decrease in temperature.

Front

What is an exothermic reaction?

Back

A reaction that releases heat to its surroundings, resulting in an increase in temperature.

Front

What happens to temperature in an endothermic reaction?

Back

The temperature decreases.

Front

What happens to temperature in an exothermic reaction?

Back

The temperature increases.

Front

What is enthalpy?

Back

Energy stored in the chemical bonds in a substance.

Front

Give an example of an endothermic process.

Back

Baking bread or cooking an egg.

Front

Give an example of an exothermic process.

Back

Burning wood or respiration in living organisms.

Front

What is the significance of the temperature change in a chemical reaction?

Back

It helps determine whether the reaction is endothermic or exothermic.

Front

What type of graph represents an endothermic reaction?

Back

A graph that shows a decrease in temperature as the reaction progresses.

Front

What type of graph represents an exothermic reaction?

Back

A graph that shows an increase in temperature as the reaction progresses.
