I got this all right surprisingly but glad i did but yes they are all 100% right when i submitted it. Just if try matching the answers to your questions because i did exactly what the answer is but not the question.
1.gas
2.molecules in solid,liquid, and gas phases
3.6.67 g/ml
4.aluminum
5.The ice cube and the glass of water have lower heat capacities than the swimming pool .
6.a chemical change
7.B and D It would'eve taken long to type
8.The table's molecules were vibrating more slowly in that area
9.The overall mass before a reaction is equal to the overall mass
10.They are different states of matter
11.Pure substances have different chemicals and physical properties
12.Its appearance changed
13.Column A shows physical changes; Column B shows chemical changes
Ok that all i can put are all the non-writing questions to this science test but i could do the one that u need put the word and write it out but i don't want to because I'm not sure if it right or not i haven't received it so yeah hope it helps!I'll probably try fixing it if there was a mistake in my answers.
