Endothermic and Exothermic Reactions

Front

What are endothermic processes?

Back

Endothermic processes are chemical reactions that absorb heat from their surroundings, resulting in a decrease in temperature.

Front

What are exothermic processes?

Back

Exothermic processes are chemical reactions that release heat into their surroundings, resulting in an increase in temperature.

Front

Give an example of an endothermic reaction.

Back

Baking bread and cooking an egg are examples of endothermic reactions.

Front

What instrument is used to measure temperature changes in reactions?

Back

A thermometer is used to detect temperature changes in endothermic or exothermic reactions.

Front

If the temperature of a reaction decreases, what type of reaction is it?

Back

It is an endothermic reaction.

Front

If the temperature of a reaction increases, what type of reaction is it?

Back

It is an exothermic reaction.

Front

In an exothermic reaction, what happens to heat?

Back

Heat is given out.

Front

What happens to energy when a candle is lit?

Back

Energy is released during the combustion of hydrocarbons in a candle.

Front

What is the main difference between endothermic and exothermic reactions?

Back

Endothermic reactions absorb heat, while exothermic reactions release heat.

Front

What is an example of an exothermic reaction?

Back

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