What is the difference between capillary action and surface tension? The surface tension acts to hold the surface intact. Capillary action occurs when the adhesion to the surface material is stronger than the cohesive forces between the water molecules. Water wants to stick to the glass and surface tension will push the water up, until […]

When you drop soap on the floor is it dirty? It doesn’t inherently do anything to make something “clean.” Dropping soap on the ground will make the soap dirty, but the dirt clinging to the soap is no longer on the ground, so technically the floor in that one spot is slightly cleaner. Does a […]

Does an atom carry a charge? An atom consists of a positively charged nucleus, surrounded by one or more negatively charged particles called electrons. The positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. What are atoms in electricity? Atoms are made up of even smaller elements, […]

What are huge loops of gas that link different parts of sunspot regions? Reddish loops of gas called prominences link different parts of sunspot regions. Sometimes the loops in sunspot regions suddenly connect, releasing large amounts of energy. The energy heats gas on the sun to millions of degrees Celsius, causing the gas to explode […]

What two factors drive the ocean conveyor belt? The global ocean conveyor belt is a constantly moving system of deep-ocean circulation driven by temperature and salinity. What are the two main types of global ocean currents and what forces drive each one? There are two main types of ocean currents: currents driven mainly by wind […]

What is Barani method? GROWING wheat in rain-fed (barani) conditions is being practiced in many countries which are getting more yield than in ours due to adoption of better management practices. The moisture collected from the monsoon rains during July and August is infiltrated into the soil and preserved for growing wheat crop. What is […]

Why can carbon atoms form long chains? Because each carbon is identical, they all have four valence electrons, so they can easily bond with other carbon atoms to form long chains or rings. In fact, a carbon atom can bond with another carbon atom two or three times to make double and triple covalent bonds […]
