Energy Transfer in Physical and Chemical Changes Quiz

15 Questions

Quiz Description

This particular quiz guides students on the fundamentals of the energy transfer that is accompanied by a physical or a chemical change. Composed of questions with four options of which one is correct. Questions which have been set based on the national curriculum for the gcse and questions that meet up to the examination standards

As we all know, a physical change changes only the appearance of a particular substance with no new substance formed whereas a chemical change causes the substance to change its appearance into a totally different substance. The energy transfer that takes place in both a physical and a chemical change is the movement of heat. For a physical change, from the surroundings, heat is absorbed into the system and for a chemical change, the heat is instead released from the system into the surroundings.

` `This quiz is just part of a set of GCSE quizzes for those that wish to go in for the gcse. Go ahead and test your knowledge with the questions below.
