ReplyDeleteHi Admin,
ReplyDeleteWith regards to Item # 7. I think the answer should be (C) law of conservation of energy and not Kinetic Theory of Matter... What do you think?
that is also what I am thinking. Let us double check the answers...if there is something wrong with the answers, i.e., this is unreliable.
