How much force can a hydraulic press produce? In case the pressure gauge reads 1000 PSI, the 1000 pounds per square inch is applied to 10 square inches. If every square inch of the surface area applies 1000 pounds of force, the 10 square inches will exert a total of 10,000 pounds of force. What […]
What is crystallization for Class 7th?
What is crystallization for Class 7th? Crystallization is a process by which a pure soluble substance separates out in the form of crystals from its hot and saturated solution on cooling. The process is employed in the separation of pure common salt from the impure common salt obtained from sea. What is the principle of […]
What is the main form of energy?
What is the main form of energy? After hundreds of years of observation and experimentation, science has classified energy into two main forms: kinetic energy and potential energy. In addition, potential energy takes several forms of its own. Kinetic energy is defined as the energy of a moving object. What is energy transferred from? Energy […]
What causes a comet to move?
What causes a comet to move? Long-period comets are set in motion towards the Sun from the Oort cloud by gravitational perturbations caused by passing stars and the galactic tide. Hyperbolic comets may pass once through the inner Solar System before being flung to interstellar space. How do I track comets? How to See Comet […]
What greenhouse gas has over 100x the efficiency of carbon dioxide to reflect light back to the earth?
What greenhouse gas has over 100x the efficiency of carbon dioxide to reflect light back to the earth? A methane molecule has 25 times the global warming potential of a CO2 molecule. A single nitrous oxide molecule has 298 times the global warming potential of a CO2 molecule. Which of the following contribute the most […]
Which jet stream is responsible for burst of monsoon?
Which jet stream is responsible for burst of monsoon? Easterly Jet Stream How jet streams are formed? Jet streams are currents of air high above the Earth. They move eastward at altitudes of about 8 to 15 kilometers (5 to 9 miles). They form where large temperature differences exist in the atmosphere. Cooler, heavier air […]
What is the major difference between simmering and poaching?
What is the major difference between simmering and poaching? Poaching is a technique typically used for delicate foods including eggs, fish and fruits. In order to poach food effectively, it must be completely submerged in water. Simmering requires the temperature of the liquid to be between 185 to 200 degrees. What food can be boiled? […]
Does the melting point increase across a period?
Does the melting point increase across a period? Melting and boiling points increase across the three metals because of the increasing strength of their metallic bonds. The number of electrons which each atom can contribute to the delocalized “sea of electrons” increases. The atoms also get smaller and have more protons as you go from […]
How does stick flex affect your shot?
Is Iron bad for copper pipes?
Is Iron bad for copper pipes? On cold-water piping, pitting and corrosion is often caused by an excess amount of flux residue. Iron deposits from a rusty water heater can also corrode copper pipes. What pH level is toxic? Toxic effects on survival, motility, and growth decreased with increasing pH. From pH 6.9 to 9.0, […]
