Thermal Energy in Chemical Reactions

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs heat from its surroundings, causing the reaction mixture to feel colder.

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases heat to its surroundings, causing the reaction mixture to feel hotter.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of the tiny particles that make up matter.

Front

What are reactants in a chemical reaction?

Back

Reactants are the substances that are initially involved in a chemical reaction.

Front

What are products in a chemical reaction?

Back

Products are the substances that are formed as a result of a chemical reaction.

Front

How does temperature change in an endothermic reaction?

Back

In an endothermic reaction, the temperature of the surroundings decreases as heat is absorbed.

Front

How does temperature change in an exothermic reaction?

Back

In an exothermic reaction, the temperature of the surroundings increases as heat is released.

Front

What is the role of thermal energy in chemical reactions?

Back

Thermal energy influences the rate of chemical reactions and the state of matter involved.

Front

What is the significance of measuring temperature changes in reactions?

Back

Measuring temperature changes helps determine whether a reaction is endothermic or exothermic.

Front

What is the relationship between reactants and products?

Back

Reactants are transformed into products during a chemical reaction.
