Why do things stick to glass? The short answer is that glass–an amorphous compound containing primarily silicon and oxygen–tends to form something known as silanol on its surface. They form hydrogen bonds with liquid water, causing it to adhere to the surface of the glass very strongly. Why does water wet glass and mercury doesn […]
How do I know if my electric motor brushes are bad?
What are the uses of units in our daily life?
What are the uses of units in our daily life? Measurement provides a standard for every day things and processes. From weight, temperature, length even time is a measurement and it does play a very important role in our lives. The money or currency we use is also a measurement. And think of the rumble […]
Which solid has the highest melting point?
Which solid has the highest melting point? tungsten Do impurities lower melting point? The presence of even a small amount of impurity will lower a compound’s melting point by a few degrees and broaden the melting point temperature range. Because the impurity causes defects in the crystalline lattice, it is easier to overcome the intermolecular […]
How do you analyze graphical data?
How do you analyze graphical data? Data Analysis & Graphs Review your data. Try to look at the results of your experiment with a critical eye. Calculate an average for the different trials of your experiment, if appropriate. Make sure to clearly label all tables and graphs. Place your independent variable on the x-axis of […]
What is needed for an ecosystem to support the greatest variety of organisms?
What is needed for an ecosystem to support the greatest variety of organisms? Answer: An ecosystem must contain producers, consumers, decomposers, and dead and inorganic matter. All ecosystems require energy from an external source – this is usually the sun. Plants need sunlight to photosynthesize and produce glucose, providing an energy source for other organisms. […]

What is the difference between subduction zones and hot spots?
What is the difference between subduction zones and hot spots? Subduction zones are areas in which oceanic plates are overridden by continental plates, forcing the heavier oceanic crust deep enough to be melted and recycled as second generation magma. Hot spots provide information about the rates and directions of movement of tectonic plates over geologic […]
Why the motion of pendulum will not be a simple harmonic motion?
Why the motion of pendulum will not be a simple harmonic motion? Any pendulum undergoes simple harmonic motion when the amplitude of oscillation is small. The pendulum still oscillates, but the motion is no longer simple harmonic motion because the angular acceleration is not proportional to the negative of the angular displacement. Why is the […]
How dangerous is a whirlpool?
How dangerous is a whirlpool? Whirlpools can be very dangerous and can cause drowning. Despite the danger, whirlpools are a fascinating natural phenomenon. Many people enjoy watching strong maelstroms spin away from the safety of dry land. Can you die from a whirlpool? The power of natural whirlpool is often exaggerated by fiction, as there […]
