Question 24

Define emergent properties

Answer 24

 Emergent Properties- novel properties arising from the way in which components interact. Emergent properties often cannot be deduced solely from the knowledge of the individual components

Question 25

What are novel properties arising from the way in which components interact. They often cannot be deduced solely from the knowledge of the individual components?

Answer 25

emergent properties
