Glossary Compound Formula Abundance percent by weight Silicon dioxide SiO2 42.86% Magnesium oxide MgO 35.07% Ferrous oxide FeO 8.97% Aluminum oxide Al2O3 6.99% How do you know the difference between a compound and mixture? Compound:a substance that is made up of more than one type of atom bonded together. […]

What is the hottest rainforest on earth? Tropical rainforests often have from 160 to 400 inches of rain a year. But they aren’t the wettest or even the hottest places on Earth. (The wettest is Mount Waialeale, in Hawaii, USA, and the hottest is Libya in North Africa.) What is the environment like in a […]

How do you calculate isothermal compression? It is also worth noting that for ideal gases, if the temperature is held constant, the internal energy of the system also is constant, and so ΔU = 0. Since the First Law of Thermodynamics states that ΔU = Q + W (IUPAC convention), it follows that Q = […]

Is normal force a centripetal force? The normal force and a component of the weight point toward the center of the loop (the component perpendicular to the loop), so they get to be the centripetal force. How is centripetal force calculated? Centripetal force is measured in Newtons and is calculated as the mass (in kg), […]

What will possibly happen when rocks bend without breaking? If rocks tend to bend without breaking, they are said to be ductile. If a rock bends but is able to return to its original position when the stress is released, it is said to undergo elastic behavior. Earthquakes and faults occur in the shallow crust, […]

What is the difference between thermal energy and temperature and heat? What is the difference between temperature, thermal energy, and heat? The term temperature refers to the average amount of heat or the motion energy of particles in a substance. It measures the hotness and coldness of a substance. Thermal energy is the total motion […]

What are the 4 types of plate boundary? Plate Boundaries and Hotspot Demonstration Divergent Plate Boundary. Volcanic eruptions and shallow earthquakes are common where plates rip apart. Convergent Plate Boundary. Transform Plate Boundary. Hotspot. What are the 5 plate boundaries? What are the major plate tectonic boundaries? Divergent: extensional; the plates move apart. Spreading ridges, […]

Why do we only have one tide a day? Also, the moon’s orbit around the Earth is tilted by about 5 degrees from the plane of Earth’s orbit around the sun. Thus, the maximum tidal bulge will usually be either above or below the equator. Sometimes, some places on Earth experience only one of the […]

Who has most natural gas? Russia How many years of natural gas are left? 52 years How long will our natural gas supply last? about 84 years Which country has most gas? Who buys Russian gas? The largest importers of Russian gas in the European Union are Germany and Italy, accounting together for almost half […]

What happens if you put too many stamps on an envelope? Yes you may use as many stamps as you wish. If they are of excess value than required then excess amount will not be refunded. What happens if you put a stamp on the wrong side? If you accidentally put the stamp on the […]
