Endothermic 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.

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.

What is a chemical change?

Back

A chemical change is a process where one or more substances are transformed into new substances with different properties.

Front

What is an example of an exothermic reaction?

Back

An example of an exothermic reaction is the combustion of fuels, such as burning wood or gasoline.

Front

What is an example of an endothermic reaction?

Back

An example of an endothermic reaction is the process of photosynthesis in plants, where sunlight is absorbed.

Front

How can you detect an exothermic reaction?

Back

An exothermic reaction can be detected using a thermometer, as it will show an increase in temperature.

Front

What happens to energy during a chemical change?

Back

During a chemical change, energy is either absorbed or released, depending on whether the reaction is endothermic or exothermic.

Front

What is the role of a catalyst in a chemical reaction?

Back

A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction; it is conserved.
