Why ionisation enthalpy of nitrogen is higher than oxygen? An atom is highly stable when its valence orbital is completely filled or half-filled and in nitrogen, the valence p orbital is exactly half filled. So, the ionization energy of nitrogen is more than that of oxygen. What is the first ionization of oxygen? First Ionization […]
What are the disadvantages of OTEC?
What are the disadvantages of OTEC? Disadvantages of OTEC system Capital investment is very high. Conversion efficiency is very low about 3-4% due to small temperature difference in between the surface water and deep water. Low efficiency of these plants coupled with high capital cost and maintenance cost makes them uneconomical for small plants. What […]
What is removed during freeze drying?
What is removed during freeze drying? OVERVIEW. Freeze drying is the removal of ice or other frozen solvents from a material through the process of sublimation and the removal of bound water molecules through the process of desorption. Which is better canning or dehydrating? Some of the main benefits of canning are: It preserves the […]
What statement is true of liquids?
What statement is true of liquids? A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure. As such, it is one of the four fundamental states of matter (the others being solid, gas, and plasma), and is the only state with […]
How do you interpret relative frequency?
How do you interpret relative frequency? A relative frequency is the ratio (fraction or proportion) of the number of times a value of the data occurs in the set of all outcomes to the total number of outcomes. To find the relative frequencies, divide each frequency by the total number of students in the sample–in […]

How did Pangea split?
How did Pangea split? Scientists believe that Pangea broke apart for the same reason that the plates are moving today. The movement is caused by the convection currents that roll over in the upper zone of the mantle. About 200 million years ago Pangaea broke into two new continents Laurasia and Gondwanaland. Which era did […]
What is the formula for calculating electrical load?
What is the formula for calculating electrical load? Compare the wattage of your air conditioner and furnace. Since you only use one at a time, add only the larger wattage rating to your equation. Divide the resulting number of watts by volts (most homes use 220 volts) to get the number of amps, or the […]
What are four ways that waves interact with matter?
What are four ways that waves interact with matter? Waves interact with matter in several ways. The interactions occur when waves pass from one medium to another. The types of interactions are reflection, refraction, and diffraction. Each type of interaction is described in detail below. What is the measure of energy in a wave? Amplitude […]
What biome is Eureka in?
