Where does wax go when you burn it? When candles burn, most of their matter goes into the air. The light and heat from a candle comes from the wax burning. When you light the wick, the flame causes some of the wax to melt, flow up the wick and evaporate, and then the wax […]
What is the result of water conservation?
What is the result of water conservation? Reducing our water usages reduces the energy required to process and deliver it to homes, businesses, farms, and communities, which, in turn, helps to reduce pollution and conserve fuel resources. It makes water available for recreational purposes. What is the importance of water conservation? Every person on earth […]
Which pair of elements are likely to form ionic?
Which pair of elements are likely to form ionic? Ionic compounds generally form between elements that are metals and elements that are nonmetals. For example, the metal calcium (Ca) and the nonmetal chlorine (Cl) form the ionic compound calcium chloride (CaCl2). In this compound, there are two negative chloride ions for each positive calcium ion. […]
Do humans have free will argument?
Do humans have free will argument? At least since the Enlightenment, in the 18th century, one of the most central questions of human existence has been whether we have free will. In the late 20th century, some thought neuroscience had settled the question. In this context, a free-willed choice would be an undetermined one. … […]
Are there any bodies in space?
Are there any bodies in space? There’s no doubt space is an extremely dangerous place, but only a handful of space travelers have actually died there. Following the only deaths to have ever occurred in space, the USSR started a policy requiring all cosmonauts to wear pressurized spacesuits during reentry. Do you poop when you […]
Is Ocean Energy expensive?
Is Ocean Energy expensive? The World Renewable Energy Report estimates the cost of wave energy at an average of 9 cents/kWh and tidal and current an average of 8 cents/kWh. Recent EPRI reports have found that, presently, the cost of power from ocean technologies ranges from 7 cents to 16 cents/kw in a low case […]
Where do hurricanes go to die?
Where do hurricanes go to die? If the hurricane wanders northward, it may move into cooler waters, which slow its growth, and eventually reduce its severity. If it moves onto land it loses that warm water source, and so dies down. The single most important factor in a hurricane losing energy is friction. What destroys […]
How are rock being classified?
How are rock being classified? Rocks are classified according to characteristics such as mineral and chemical composition, permeability, texture of the constituent particles, and particle size. This transformation produces three general classes of rock: igneous, sedimentary and metamorphic. Those three classes are subdivided into many groups. How do you classify the three types of rocks? […]
What is greatest potential energy?
What is greatest potential energy? Higher objects (with further to fall) have greater potential energy. The heaviest of 2 objects at the same height has the greatest gravitational potential energy. Does a pendulum have rotational kinetic energy? By the parallel axis theorem, a pendulum that rotates around a point P and a distance l from […]
What are two units used to measure density?
What are two units used to measure density? Density has the units of mass divided by volume such as grams per centimeters cube (g/cm3) or kilograms per liter (kg/l). Which statement best describes how you measure density? Well, the density of an object is how relatively heavy an object is at a fixed volume. Mathematically, […]
