endothermic and exothermic reactions

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs heat from its surroundings.

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases heat to its surroundings.

Front

How can you detect an endothermic or exothermic reaction?

Back

You can detect an endothermic or exothermic reaction using a thermometer to measure temperature changes.

Front

What happens to the temperature of the surroundings during an endothermic reaction?

Back

The temperature of the surroundings decreases, making it feel cooler.

Front

What happens to the temperature of the surroundings during an exothermic reaction?

Back

The temperature of the surroundings increases, making it feel warmer.

Front

What is the law of conservation of energy in relation to chemical reactions?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another during a chemical reaction.

Front

What is the role of activation energy in chemical reactions?

Back

Activation energy is the minimum energy required for a chemical reaction to occur.

Front

What is a chemical reaction?

Back

A chemical reaction is a process in which substances undergo chemical changes that result in the formation of new substances.

Front

What is the difference between reactants and products in a chemical reaction?

Back

Reactants are the starting substances in a chemical reaction, while products are the substances formed as a result of the reaction.

Front

What is a calorimeter used for?

Back

A calorimeter is an instrument used to measure the heat absorbed or released during a chemical reaction.
