can be found naturally in all three of its states. However its molecules are bonded together by hydrogen bonds‚ this raises its melting and boiling points‚ i.e. its boiling point would be -120¢ªC rather than 100¢ªC. Also because it contains slightly negatively charged oxygen atoms and slightly positively charged hydrogen atoms making it polar. <br> <br>Water has been called a universal solvent because of it polarity. This means it can easily ionise substances‚ Many compounds‚ whether ionic‚ polar or

Problem: In my science project the experiment answers three questions. One question is which material of cup makes the soundwaves more clear. The second question is what pitch of sound makes the most condensed sound pattern on the water. The third question is how loud does the speaker need to be to make a pattern show up on the water’s surface. Hypothesis: I think that a styrofoam cup will make the sound patterns most clear out of all the materials of cups. I think this because when you slide
