One thing that does not change is the chemical composition of water, which is still H2O. And maybe mass, if all of the particles remain inside the beaker, which was never mentioned in the question so I am not sure.
You're right, it's a solid at room temperature :)
Answer:
See below.
Explanation:
The volume increases.
This is complies with Boyles Law:
At constant temperature P1 V1 = P2 V2 where P1, P2 are the pressures before and after and V1 and V2 are the volumes before and after.
Nobody knows this answer I checked a bunch of websites and they all don't know the answer.
Answer:
Independent Variable: The thing in an experiment which is changed.
Dependent Variable: The thing in an experiment which is affected by the change. (In other words, it's affected by the independent variable.)
Control Variable: The other factors of the experiment that remain unchanged.
For example, say you want to do an experiment about the effects of water on plant height. So, the independent variable, or the thing that is changed would be the amount of water, and the dependent variable would be the plant height, as the plant height is directly affected by the independent variable. Lastly, for this to be a fair experiment, there must be control variables. For example, all of the plants should be put in a room with equal temperature, they should get the same amount of sunlight, etc.
I hope this answers your question- feel free to ask me if you need any more help.
