How can you increase the density of ice? Molecular basis for the Volume Increase of Ice: The normal pattern for most compounds is that as the temperature of the liquid increases, the density decreases as the molecules spread out from each other. As the temperature decreases, the density increases as the molecules become more closely […]
Why are low-density lipoproteins bad?
Why are low-density lipoproteins bad? LDL (low-density lipoprotein), sometimes called “bad” cholesterol, makes up most of your body’s cholesterol. High levels of LDL cholesterol raise your risk for heart disease and stroke. Which is worse triglycerides or LDL?

Which opening will cause the greatest diffraction?
Which opening will cause the greatest diffraction? Since light waves are small (400 to 700nm), diffraction only occurs through small openings or small grooves, with the greatest diffraction occurring when the size of the opening is the same order of magnitude as the wavelength of light. Smaller openings = more diffraction. What is the frequency […]

What is the measure of wave energy?
What is the measure of wave energy? The standard measurement of energy in science is the joule. The amount of energy in a wave depends on its height and wavelength as well as the distance over which it breaks. Given equal wavelengths, a wave with greater amplitude will release more energy when it falls back […]
