Unit 2 Flashcard Prep

Front

What are constraints in design?

Back

Constraints are limitations or rules that must be followed during the design process.

Front

What is temperature?

Back

Temperature is a measure of the average energy of motion of the particles of a substance.

Front

What is a chemical reaction?

Back

A chemical reaction is a process that changes one set of chemicals into another set of chemicals.

Front

What happens to particles during a chemical reaction?

Back

During a chemical reaction, particles break apart and reform as new substances.

Front

What are criteria in design?

Back

Criteria are the things a design needs to do in order to be successful.

Front

Define phase change.

Back

Phase change is the transition of a substance from one state of matter to another, such as solid to liquid.

Front

What is an endothermic reaction?

Back

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

Front

What is the difference between a physical change and a chemical change?

Back

A physical change alters the form of a substance but not its chemical composition, while a chemical change results in the formation of new substances.

Front

What is energy transfer?

Back

Energy transfer is the movement of energy from one place or object to another.

Front

What is the role of criteria in engineering design?

Back

Criteria guide the design process by outlining the necessary features and functions for success.
