Homework Answers
Answer: c. Gas
Intermolecular forces in gaseous state particles are negligible.. these particles can move randomly in the space available for them.However when mass of gaseous substance is significant then there will be an influence of their IMF
In gaseous state particles are separated by fairly large distances and hence the intermolecular forces among them are negligible
