What is the most important thing in science? In order to do scientific activity, to know the truth of nature through study or research, scientist must do that based on empiricism, experimentation and methodological. Those three foundations in science are integrated into a so-called scientific method. This is the most important thing in science. What […]

Did Antarctica used to be hot?
Did Antarctica used to be hot? Climate change Some of Antarctica has been warming up; particularly strong warming has been noted on the Antarctic Peninsula. A study by Eric Steig published in 2009 noted for the first time that the continent-wide average surface temperature trend of Antarctica was slightly positive from 1957 to 2006. Did […]
What happens during the formation of a solution?
What happens during the formation of a solution? In order to form a solution, the solute must be surrounded, or solvated, by the solvent. Solutes successfully dissolve into solvents when solute-solvent bonds are stronger than either solute-solute bonds or solvent-solvent bonds. What are the factors affecting solution? Factors affecting solubility Temperature. Basically, solubility increases with […]

More reactant particles moving together allow more collisions to happen and so the reaction rate is increased. The higher the concentration of reactants, the faster the rate of a reaction […]
What are observable and measurable properties of matter?
What are observable and measurable properties of matter? Observable properties include measurements like height, weight, temperature, and the volume of an object. Explanation: Observable properties are things we can use our five senses to determine, the measurable properties in the question need a tool like a thermometer or a ruler to determine. What are the […]
What is the main cause of volcanic activity?
What is the main cause of volcanic activity? Volcanoes erupt when molten rock called magma rises to the surface. Magma is formed when the earth’s mantle melts. If magma is thick, gas bubbles cannot easily escape and pressure builds up as the magma rises. When the pressure is too much an explosive eruption can happen, […]
