first question you should ask youeself is: what is a theory and what is a hypothesis? do you know?
yes i have it in front of me while im doing a practice test
A hypothesis consists either of a suggested explanation. In science, a theory is a well-substantiated, unifying explanation for a set of verified, proven hypotheses. As opposed to theory, a hypothesis needs to be testable and falsifiable. Now, which answer correctly defines this?
the third on e i think
am i correct
its the first, its a theory therefore its based on fact rather than random guessing
oh thank you i dident read that one ops thank you
you are welcome, i just hope you understood my explanation
A tested hypothesis that works, may become part of a theory or become a theory itself. The testing should be an attempt to prove the hypothesis is wrong.
yes it helps more than yahoo answers thats for sure and i did understand it
can some one help me with this other question please
As liquid water freezes, the molecules arrange themselves in a way that takes up more space than liquid water. What would most likely occur if the arrangement of frozen water molecules required less space than that of liquid water molecules? The density of ice would be greater than the density of liquid water, and ice would not float. Ice would form in layers, and liquid water would get trapped in between the layers. Liquid water would have a higher specific heat, making it less likely to undergo vaporization. The freezing point of water would decrease, making ice more difficult to form.
I think it would be best to close this question and ask another separately. You are likely to get more answers from others.
