One property of water that makes life possible on earth is its solid state‚ (frozen).Water is less dense as a solid than it is as a liquid‚ which enables ice to float. When its temperature falls below 4 degrees Celsius‚ the molecules slow down to a point where they are not moving fast enough in order to break the hydrogen bonds‚ therefore making the bonds more stable. The bonds then are farther apart‚ making the solid less dense. Water is one of the few molecules that has this property‚ allowing

Feels course. Some grains look more uniform to each other than others do.Wet: did not dissolve. Seemingly unchanged. | d) Oil and water on plastic | Oil: expands evenly into almost perfect circle‚ takes longer to reach max expansion

First thing is to make your hypothesis on how to filter dirty water like mine “My hypothesis is if I use one cut bottle and layer it to be pebbles‚ sand‚ cloth‚ charcoal‚ then cloth‚ sand‚ and pebbles it filter the water will be cleaned.”. Then you start to build hypothesis‚ so start by getting a bottle‚ cut the bottom of the bottle like two inches of it. You take the cap off the bottle then get two coffee filter and use two rubber bands to tie it to the cap of the bottom. Then add about a inch of

Derricka Joe Period 5 1 Oct.‚ 2014 Lab Experiment One: Physical Properties Lab Analysis: For our first unknown‚ we observed the color and odor of the substance. The substance was a clumpy‚ white‚ crystal-like substance and it smells like new plastic. When we tested the solubility in water it resulted insoluble and in ethanol it resulted soluble. This substance could not be tested for electrical conductivity because the water was insoluble. We then tested for the PH value and it was neutral. The

My experiment was to find out how the type of liquid can affect the amount of drops that can fit on a penny. I used 3 liquids to test my question and they were water‚ rubbing alcohol‚ and vegetable oil. I discovered that water could hold the most drops and vegetable oil and rubbing alcohol could hold about the same amount of drops. My hypothesis was if I use water then it will hold more drops than vegetable oil. My hypothesis was supported by my data. The average number of drops for water was 93
