Endothermic vs. Exothermic Reactions Intro Practice

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 of the surroundings.

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 of the surroundings.

Front

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

Back

The temperature of the surroundings decreases.

Front

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

Back

The temperature of the surroundings increases.

Front

In an endothermic reaction, is heat taken in or given out?

Back

Heat is taken in.

Front

In an exothermic reaction, is heat taken in or given out?

Back

Heat is given out.

Front

What would you feel if you touched a beaker containing an endothermic reaction?

Back

You would feel the beaker is cold.

Front

True or False: In an endothermic reaction, the system is releasing energy.

Back

False. In an endothermic reaction, the system is absorbing energy.

Front

Give an example of an endothermic reaction.

Back

Photosynthesis is an example of an endothermic reaction, where plants absorb sunlight to convert carbon dioxide and water into glucose.

Front

Give an example of an exothermic reaction.

Back

Combustion of fuels, such as burning wood or gasoline, is an example of an exothermic reaction, where heat is released.
