Does aluminum cool down fast?
Does aluminum cool down fast? The heat energy stored in it increases in proportion to its mass. This allows aluminum to dump its thermal energy into the air surrounding it very quickly. So not only does aluminum not hold much thermal energy, it also dumps it super quickly. Together, these mean that aluminum foil cools […]
Are moles conserved in a chemical reaction?
Are moles conserved in a chemical reaction? A chemical reaction, balanced in terms of moles, contains the same number of atoms of each element, before and after the reaction. This means that all the atoms and its masses are conserved. Why are moles not conserved during a chemical reaction? But the moles of EACH ATOM […]
Is velocity directly proportional to tension?
Is velocity directly proportional to tension? From equation (2) we see that the square of the wave velocity is, in turn, directly proportional to the tension, since the linear density μ is constant in this experiment. It follows that the square of the wavelength should be directly proportional to the tension. Does tension affect velocity? […]
Does every collision between reacting particles lead to products?
Does every collision between reacting particles lead to products? Reacting particles can form products when they collide with one another provided those collisions have enough kinetic energy and the correct orientation. Particles that lack the necessary kinetic energy may collide, but the particles will simply bounce off one another unchanged. What is the difference between […]
Is methane hydrate bad for the environment?
Is methane hydrate bad for the environment? Climate change impacts on methane hydrates Climate warming, however, could cause the hydrates to destabilize. The methane, a potent greenhouse gas, would escape unused into the atmosphere and could even accelerate climate change. Is methane clean burning? Natural gas, which primarily consists of methane, is the cleanest burning […]
Does hydrogen have a positive or negative charge?
Does hydrogen have a positive or negative charge? A hydrogen ion is formed when a hydrogen atom loses an electron and therefore becomes positively charged (it has a charge of +1). A hydrogen atom is therefore often referred to as just a proton, as it is left with only one proton and no electrons, as […]
What is the weight of a 25 kg object on earth?
What is the weight of a 25 kg object on earth? The mass would be definitely the same. This Wiki article on Weightlessness would be useful… There are different system of units like gravitational,SI, MKS. I have seen in some text as slug as the unit of mass in gravitational system.So mass of 25 kg […]
How are art and science similar and different?
How are art and science similar and different? Arts and science are similar in that they are expressions of what it is to be human in this world. Both are driven by curiosity, discovery, the aspiration for knowledge of the world or oneself, and perhaps, as the conceptual artist Goshka Macuga said on her recent […]
What is the magnetic domain theory?
What is the magnetic domain theory? The domain theory states that inside a magnet there are small regions in which the magnetic direction of all the atoms are aligned in the same directions. These regions are known as domains. Within a domain, the aligment of the magnetic direction is the same. How do you identify […]
