What are examples of ratio variables? Examples of ratio variables include: enzyme activity, dose amount, reaction rate, flow rate, concentration, pulse, weight, length, temperature in Kelvin (0.0 Kelvin really does mean “no heat”), survival time. What are the 5 most common process variables? The most common process variables fall into five major types: level, flow, […]
Why can some mixtures be separated by chromatography?
Why can some mixtures be separated by chromatography? Chromatography can be used to separate mixtures of coloured compounds . As the solvent soaks up the paper, it carries the mixtures with it. Different components of the mixture will move at different rates. This separates the mixture out. How many main ways are there to separate […]

What do theories and laws have in common?
What do theories and laws have in common? As previously stated, a scientific theory is a well-substantiated explanation of some aspect of the natural world. A scientific law is simply an observation of the phenomenon that the theory attempts to explain. The theory of gravity is the explanation as to why the apple falls to […]
Do elements in Group 1 gain or lose electrons?
Do elements in Group 1 gain or lose electrons? All Group 1 atoms can lose one electron to form positively charged ions. For example, potassium atoms do this to form ions with the same electron configuration as the noble gas argon. Group 2 atoms lose two electrons to form positively charged ions. Most elements in […]
Where is UV found?
Where is UV found? UV radiation is present in sunlight, and constitutes about 10% of the total electromagnetic radiation output from the Sun. It is also produced by electric arcs and specialized lights, such as mercury-vapor lamps, tanning lamps, and black lights. What is UV color? UV light has a shorter wavelength than visible light. […]

What is Charles Law in simple terms?
What is Charles Law in simple terms? Charles’s law, a statement that the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature, if the pressure remains constant. It is a special case of the general gas law and can be derived from the kinetic theory of gases under the […]
