Why does a straw look bigger in water? Place a straw in a glass of water, and behold: It looks broken. But below, when the light also travels through water, the refraction causes the image of the straw to be in a slightly different location. The water also acts as a type of magnifying lens, […]
How many protons and electrons are in oxygen?
How many protons and electrons are in oxygen? 8 Is the number of nucleons equal to the number of electrons? The atomic number gives the number of protons in the atom. The number of nucleons gives the total number of protons plus neutrons in the atom. Since an atom is electrically neutral, an atom has […]

What are the features of a sedimentary rock?
What are the features of a sedimentary rock? Sedimentary rocks contain rounded grains in layers. The oldest layers are at the bottom and the youngest layers are at the top. Sedimentary rocks may contain fossils of animals and plants trapped in the sediments as the rock was formed. What type of minerals are found in […]
Why diffusion is faster in water?
Why diffusion is faster in water? This is because in hot water, the water molecules have more energy and are moving faster than the molecules of cold water. Because diffusion happens from high concentration to low concentration, the more molecules are moving, the more opportunities they have to mix together. What is the slowest diffusing […]
What happens if centrifuge is not balanced?
What happens if centrifuge is not balanced? Centrifuges, which operate at high speed, have great potential for injuring users if not operated properly. Unbalanced centrifuge rotors can result in injury or death. Sample container breakage can release aerosols that are harmful if inhaled. What is the principle of centrifuge? A centrifuge works by using the […]
What is gamma spectroscopy used for?
What is gamma spectroscopy used for? Gamma-ray (γ-ray) spectroscopy is a quick and nondestructive analytical technique that can be used to identify various radioactive isotopes in a sample. In gamma-ray spectroscopy, the energy of incident gamma-rays is measured by a detector. How do we measure gamma rays? Scientists can use gamma rays to determine the […]
