Note: Some solids, liquids, and gases are made of atoms, and some are made of molecules. They don't stay in the same shape, they flow over eachother. Chapter 3 and Chapter 4 will go into more depth about the structure of atoms and molecules and will use more detailed models to represent them. Use the density equation to work out the density of the liquid. The goal is for students to begin thinking about water, or any substance, on the molecular level and to conclude that water molecules must be attracted to one another. They vibrate in their fixed positions, not changing shape, so they are the least energetic of the states of matter. What are the 5 elements of nucleic acids? Print two Water Drops Unite sheets for each group. The major relationship between DNA and protein is that DNA encodes the information that is necessary to synthesize proteins. The flat section of a temperature - time graph shows the melting or boiling point of a substance, as the energy transferred to the substance when it changes state is called latent heat, where the substance doesn't change temperature.
