I give 5 stars for this website.Very very helpful. Happy to know that these websites for learning exists. I scored 20/23. Tomorrow I have chemistry exam. This will be helpful for my exam….ЁЯе░
Ya this is a very good app to check whether you’re prepared or not. It helped me a lot!
Sorry I got 22/23
My bad
Pretty good website
wow nice app
Are you seriously a topper?
i got 23 out of 23 wonderful app
23/23 due to pw neev and very thankful to evidyarthi
Wow ..i got 21 from 23
Very useful for Sci exam ЁЯСП
there are 5 types but we are surrounded by 3 types of matter
This test helped to score full mark in chemistry exam
Science cbse board
There are 5 states of matter:-
BEC-Bose Einstein condensate
Plasma
Solid
Liquid
Gas
Love you all who are answering this question with lots of patience
there are 4
Last answer will be option D as plasma is fourth state of matter which is around us in neon light and bulb.
Bro… There are three states of matter…beleive it or not ЁЯШВ
This is very good AAP
helps me get good marks in my exam
