Review: Most Missed on Unit 3 - Conservation of Mass and Energy

A collection of vocabulary flashcards covering key concepts in chemistry related to the conservation of mass and energy in chemical reactions.

Heat transfer

The movement of heat from one substance to another, impacting temperature change.

Endothermic reaction

A reaction that absorbs heat from the surroundings, resulting in a temperature decrease.

Exothermic reaction

A reaction that releases heat into the surroundings, resulting in a temperature increase.

Conservation of mass

The principle stating that mass cannot be created or destroyed in a chemical reaction.

Chemical change

A process where one or more substances are altered into one or more new and different substances.

Physical change

A change that affects one or more physical properties of a substance without altering its chemical composition.

Dissolution

The process of dissolving a solute in a solvent to form a solution.

Chemical reaction

A process in which reactants are transformed into products.

Observational data

Information gathered through observation, often used to analyze chemical reactions.

Feedback loop

A process where the output of a system feeds back into the system as input, often used in analyzing experimental results.
