What is the correct order of events during primary succession? both the biotic and the abiotic components of the local environment. the rise and fall of air masses, evaporation of moisture, the seasons. What happens in primary succession? Primary succession occurs in essentially lifeless areas—regions […]
Why does Physisorption decrease with increase of temperature?
Why does Physisorption decrease with increase of temperature? As the surface area of adsorbent increases, the rate of this process increases. Extent of physisorption is more in finely divided metal particles or in porous materials. This is an exothermic process that means heat is evolved in this process. So, the rate of physisorption decreases with […]

What happens to drag when speed increases?
What happens to drag when speed increases? With an increase in speed comes an increase in drag and a decrease in net force. This decrease in net force reduces acceleration. What is the perfect aerodynamic shape? For speeds lower than the speed of sound, the most aerodynamically efficient shape is the teardrop. The teardrop has […]
What happens to current flow when voltage is increased?
What happens to current flow when voltage is increased? The current is directly proportional to the voltage and inversely proportional to the resistance. This means that increasing the voltage will cause the current to increase, while increasing the resistance will cause the current to decrease. Why does Amp go down with voltage? Amps go up […]
Is ABS active or passive?
Is ABS active or passive? Anti-lock braking systems (ABS) are active safety features designed to help drivers retain steering control by preventing wheels from locking up during an episode of heavy braking. Wheel lock means that the wheels of the vehicle have stopped rotating and as a result the vehicle begins to slide. What are […]

What are 3 things a graph must have?
What are 3 things a graph must have? Essential Elements of Good Graphs: A title which describes the experiment. The graph should fill the space allotted for the graph. Each axis should be labeled with the quantity being measured and the units of measurement. Each data point should be plotted in the proper position. A […]
What happens when sodium is mixed with water?
What happens when sodium is mixed with water? Reaction of sodium with water Sodium metal reacts rapidly with water to form a colourless solution of sodium hydroxide (NaOH) and hydrogen gas (H2). The reaction is exothermic. During the reaction, the sodium metal may well become so hot that it catches fire and burns with a […]
