Invasive Species. Over-exploitation of Species. Global Warming and Climate Change. Pollution. Human Overpopulation. Natural Calamities. Genetic Pollution. What are the major factors that are responsible for […]

What is the change in internal energy of 10 J of heat? Hence the change in internal enrgy is −10J. What is the change in internal energy of a system if the system? The first law of thermodynamics states that the change in internal energy of a system equals the net heat transfer into the […]

What were the instrument used in preparing the newest four element? Cyclotrons were the devices used to bombard heavy elements with the nuclei of light elements, mostly calcium, in order to form a few atoms of these new and very unstable elements, the presence of which could be proven but the physical properties of which […]

What is the slowest carbon cycle process? The slowest part of the cycle involves carbon that resides in sedimentary rocks, where most of Earth’s carbon is stored. When in contact with water that is acidic (pH is low), carbon will dissolve from bedrock; under neutral conditions, carbon will precipitate out as sediment such as calcium […]

What is the red liquid inside a thermometer? Mercury Does hot water rise or sink? Any object or substance that is less dense than a fluid will float in that fluid, so hot water rises (floats) in colder water. Any object or substance that is more dense than a fluid will sink in that fluid, […]

How do I know if I have fair or light skin? Fair Skin Tones: You are very fair or have porcelain skin, and burn very easily. You may be very blonde and have pale eyes, or have very dark hair and a porcelain complexion. Light Skin Tones: Your skin is pale, and you burn and […]

Does salt melt faster than sugar? Salt will always melt ice quicker than both of them. This is because in the same amount or volume, there are more molecules of salt than sugar or baking soda due to the chemical make-up. Salt, baking soda, and sugar will all act to lower the freezing point of […]

What are the 3 major areas of ethics? The field of ethics (or moral philosophy) involves systematizing, defending, and recommending concepts of right and wrong behavior. Philosophers today usually divide ethical theories into three general subject areas: metaethics, normative ethics, and applied ethics. What are the categories of ethics? There are three categories of ethical […]

What is the normal body temperature expressed in metric terms? The normal core body temperature of a healthy, resting adult human being is stated to be at 98.6 degrees fahrenheit or 37.0 degrees celsius. What is the healthiest human temperature? The average normal body temperature is generally accepted as 98.6°F (37°C). Some studies have shown […]

Is a refractor better than a reflector? Each telescope has its own advantage, for instance the refractor is better for observing the planets and the moon and the reflector for deep-sky objects (e.g. galaxies). This, however, is only noticeable in refractors with an aperture (diameter of objective lens) of 10cm (4″) or more. What are […]
