Do polar molecules have to be asymmetrical? Polar molecules MUST have an asymmetrical structure to be polar, because symmetry cancels out net charge. Asymmetrical molecules are always polar. Symmetrical molecules can be polar and non-polar. Polarity is dependent on the difference in electronegativity of the molecule’s atoms and shape. What is an example of asymmetrical? […]

Can wood exist as a liquid?
Can wood exist as a liquid? As a result of the chemical, irreversible breakdown of its components, wood does not melt. Although the water and volatile matter would evaporate in the vacuum, the long cellulose fibers in wood would strongly inhibit wood’s transition to the liquid state. Can everything be a liquid? Yes, every element […]
Why is burning of candle is both physical and chemical change?
Why is burning of candle is both physical and chemical change? Wax of the candle is made of carbon and hydrogen which reacts with oxygen on burning and changes into carbon dioxide gas and water which escapes into the air. This is a chemical change. As a result, candle melts and reduces in size. This […]
What characteristics are used to identify metamorphic rocks?
What characteristics are used to identify metamorphic rocks? Metamorphic rocks were once igneous or sedimentary rocks, but have been changed (metamorphosed) as a result of intense heat and/or pressure within the Earth’s crust. They are crystalline and often have a “squashed” (foliated or banded) texture. What is the classification of igneous rocks based on quizlet? […]
Does current always flow in a loop?
Does current always flow in a loop? Current doesn’t have to flow in a loop, if something is losing charge (like an hot electron plate in space) the charge leaves and never comes back because the electrons boil off. Current is defined by amperes law you could imagine drawing a surface around the plate and […]
What does a sign in the Device Manager indicate?
What does a sign in the Device Manager indicate? On Windows 10, sometimes, Device Manager will show a device with a yellow exclamation mark. When this happens, it indicates that the system has encountered a problem with that particular piece of hardware. Usually, it comes down to a hardware conflict of some sort, or missing […]

Does blue light have a higher frequency than green?
Does blue light have a higher frequency than green? Blue light has a shorter wavelength and therefore a higher frequency. Blue light has a shorter wavelength and therefore a higher frequency as compared to green light. Some reptiles can see light of shorter wavelengths than humans can see. Which is the least refracted Colour in […]
