Endothermic and Exothermic Assessment

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.

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.

Front

What is a product in a chemical reaction?

Back

A product is a substance that is formed as a result of a chemical reaction.

Front

What is a reactant in a chemical reaction?

Back

A reactant is a substance that undergoes change during a chemical reaction.

Front

What happens to temperature in an endothermic reaction?

Back

In an endothermic reaction, the temperature of the surroundings decreases.

Front

What happens to temperature in an exothermic reaction?

Back

In an exothermic reaction, the temperature of the surroundings increases.

Front

Give an example of an endothermic reaction.

Back

An example of an endothermic reaction is grilling a hamburger.

Front

Give an example of an exothermic reaction.

Back

An example of an exothermic reaction is burning wood.

Front

What is the main difference between endothermic and exothermic reactions?

Back

The main difference is that endothermic reactions absorb heat, while exothermic reactions release heat.

Front

What is the significance of heat in chemical reactions?

Back

Heat plays a crucial role in determining whether a reaction is endothermic or exothermic.
