What is powered by steam? In steam. Steam power constitutes an important power source for industrial society. Water is heated to steam in power plants, and the pressurized steam drives turbines that produce electrical current. The thermal energy of steam is thus converted to mechanical energy, which in turn is converted into… How fast did […]
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 […]

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 […]

How can we protect the cryosphere?
How can we protect the cryosphere? By quickly taking steps to curb emissions from cookstoves, forest burning, fossil fuel extraction and diesel transport countries could help preserve the cryosphere while at same time saving the lives and health of millions. What would happen if the cryosphere melted? Unsurprisingly, water from the current cryosphere melt is […]
What happens when something reaches absolute zero?
What happens when something reaches absolute zero? At zero kelvin (minus 273 degrees Celsius) the particles stop moving and all disorder disappears. Thus, nothing can be colder than absolute zero on the Kelvin scale. Physicists have now created an atomic gas in the laboratory that nonetheless has negative Kelvin values. What determines the state of […]
