Can humans see the full color spectrum? In a manner of speaking, we all can see infrared photons The lens normally blocks ultraviolet light, so without it, people are able to see beyond the visible spectrum and perceive wavelengths up to about 300 nanometres as having a blue-white colour. What percentage of the visible light […]

What are 4 main ways weathering can happen?
What are 4 main ways weathering can happen? There are four main types of weathering. These are freeze-thaw, onion skin (exfoliation), chemical and biological weathering. Most rocks are very hard. However, a very small amount of water can cause them to break. How long does it take for water to erode rock? This process happens […]

How does something get magnetized?
How does something get magnetized? To become magnetized, another strongly magnetic substance must enter the magnetic field of an existing magnet. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a […]

What is the effect of temperature on surface tension and why?
What is the effect of temperature on surface tension and why? In general, surface tension decreases when the temperature increases because cohesive forces decrease with an increase in molecular thermal activity. The influence of the surrounding environment is due to the adhesive action liquid molecules have at the interface. What is the effect of impurity […]
