What is the average kinetic energy of particles of matter called? Temperature At what temperature is there no kinetic energy? Absolute zero is the temperature at which the motion of particles theoretically ceases. Absolute zero has never been attained in the laboratory, but temperatures on the order of 1×10−10K have been achieved. What is the […]

What is the difference between a primary consumer and a secondary consumer and tertiary? The main difference between primary secondary and tertiary consumers is that primary consumers are the herbivores that feed on plants, and secondary consumers can be either carnivores, which prey on other animals, or omnivores, which feed on both animals and plants, […]

How long is the fall equinox? 12 hours What happens on the autumnal equinox? Autumnal equinox, two moments in the year when the Sun is exactly above the Equator and day and night are of equal length; also, either of the two points in the sky where the ecliptic (the Sun’s annual pathway) and the […]

Is it harder to get in as a transfer student? Looking broadly at four-year schools across the U.S., transfer students may have slightly more difficulty getting in. According to a report from the National Association for College Admission Counseling, the average rate of admission for a transfer applicant is 62 percent. How hard is it […]

How can you increase the kinetic energy of a substance? Whenever something becomes warmer, the kinetic energy of its atoms or molecules has increased. When matter gets warmer, the atoms or molecules in the matter move faster. It’s easy to increase the kinetic energy in matter. How does the kinetic energy of the molecules in […]

Is it a good idea to stretch sore muscles? “Stretching helps break the cycle,” which goes from soreness to muscle spasm to contraction and tightness. Take it easy for a few days while your body adapts, says Torgan. Or try some light exercise such as walking or swimming, she suggests. Keeping the muscle in motion […]

What was a serious ethical issue regarding the Little Albert experiment quizlet? according to today’s ethical standards, the nature of the study itself would be considered unethical, as it did not protect Albert from psychological harm, because its purpose was to induce a state of fear. Many sources claim that Little Albert was used as […]

Is diorite volcanic or plutonic? It is produced in volcanic arcs, and in mountain building where it can occur in large volumes as batholiths in the roots of mountains (e.g. Scotland, Norway). Because it is commonly speckled black and white, it is often referred to as “salt and pepper” rock. Diorite is the plutonic equivalent […]

Why are molecular crystals soft and with low melting point? Because the intermolecular interactions in a molecular solid are relatively weak compared with ionic and covalent bonds, molecular solids tend to be soft, low melting, and easily vaporized (ΔHfus and ΔHvap are low). What holds molecules together in a solid? Solids are generally held together […]

What kind of microscope can see a Tardigrades? Monocular Compound Microscope Can Tardigrades live in the human body? Despite their reputation, tardigrades aren’t entirely indestructible. They cannot survive the trip through the human digestive tract since our stomach acid disintegrates the flesh of the tardigrade without much trouble, so eating one wouldn’t do any harm. […]
